When I purchased the car it had a MoMo race wheel & HKB hub. Upon removing those, I found two wires, both female spade connectors, which I'm assuming are the Pos (green) and Neg (black) for the horn. However, all that was left behind is what you can see attached to the steering column, a plastic piece with copper tracing on it, and the two pieces in my hand. I'm curious as to if anyone can chime in and say exactly what those are, (I'm sure they have to be aftermarket) and exactly what part I would need to order to be able to have a working horn again.

The plug on the OEM wheel side is a three pin connector (one wire only though, no SRS) So I'm assuming whatever I need to buy would have the corresponding part that would plug into.

Can someone point me in the right direction?

 

interesting they have a little dummy clock spring thing just for the horn, F100-66-SP0. maybe you get get yours back together?

 

Thank you J9!

Are you saying those two uh...things that I'm holding, are actually an OEM clockspring? I'd have no idea how to wire that up. I know its beyond simple, the black is likely ground and green is the hot wire, but I don't know where each wire needs to connect to. One I know has to connect to the switch on the horn, but for the ground, I'm at a loss here.

 

So, looking into this more deeply, I'm kind of at a loss as to which one I need specifically. My car is a Type RB Bathurst-X, which means it came with a momo wheel from the factory (though the momo wheel that was on it is NOT the factory wheel.)

Looking at the parts picture you posted J9, that part number would make sense. However, I did some more digging and under nenguns parts catalog I found what looks to be the Bathurst-X wheel under the
"3200-steering Wheel (leather, Peach) Part Diagrams."

In that (which I've attached below) there is a part that I've hightlighted in red that looks vaguely similar to the "Clockspring" I've pulled off my car (but mine has two distinct spade connectors, which are aftermarket.)

So I'm curious, do I order F100-66-SP0 and hope it has a connector for my Efini wheel to plug into and thus allows me to regain my horn functionality?

Or do I try and order the piece thats highlighted below? I would think that since I have the Efini wheel now, I should order the regular, non momo part, the F100-66-SP0. But how would I know if that has a connector to connect to the wheel to begin with?

 

Do you have the OEM wheel in hand now?

 

I have the Efini wheel in hand. The car came with the momo wheel as it was a bathurst-x, which I do not have. I have an aftermarket momo wheel with an hkb hub that came on the car, and an Efini wheel I put on it afterwards.

 

i looked at the 66-SPO again, and i don't think its for you? the 60-253 in your pic looks like the one without it

i would try 32-98X (F124-32-98) and that should just work?

 

The 32-98x looks like it is meant for the Momo factory wheel, though. I now have an Efini OEM wheel, and that is the one I'm trying to fit. So, since I'm trying to fit the oem Efini wheel and not the factory Bathurst-X momo wheel, should I try the 66-SPO? There's no connector on the car side for any horn button, all I have are the pieces I took a picture of that someone hacked up and put spade connectors on.

 

oh good point, you need the 66-SP0 and 60-253

 

Looks like thats what I'm ordering then!

Do you happen to know what fasteners I'd need? It shows one in the box around the 66SP0, but it doesn't list a part number. I'm not sure what I'd need to bolt it in.

Also, very weird scenario here... The Horn pad doesn't want to sit flush with the wheel...at all. Either the two cylindrical looking screw/plastic things on the horn pad fit into their respective places, or the third one on the bottom of the horn pad fits flush with the wheel, all three of them will not sit flush and allow me to screw in the one bolt that holds the horn pad to the wheel. Any ideas?

 

The diagrams you are showing above are for "Airbag Nashi" (No airbag. Do you have he diagram for the standard airbag wheel? Do you have the stock clockspring for the stock efini wheel?

On The dash side you may only have the connector for the airbag nashi set-up?


Do you have airbags now?

You may have to jerry-rig the efeni wheel connectors to the airbagnashi connector somehow.

Automatic efini came with the USDM wheel.. So there are two types of efini wheels as a result.

Which do you have?

 

My car didn't come with an airbag as far as I know. I don't believe the Bathurst-X did in 1995. I know for 96 the Momo wheel has SRS.

There's no airbag connector on my car. The only thing that was on there that functioned as a horn connector was what I am holding in the pictures above, and what I think is the same thing that's highlighted in red in the parts diagram as 32-780A. The wheel I have that I am trying to install (well, its already installed, I'm trying to get the horn functional) is the non airbag/srs wheel.

I don't believe I have the clockspring for the non airbag Efini wheel, you can see in my photos whats on the steering column in the background. I think I'm missing 66-SP0 like J9 mentioned earlier, that to me looks like the clockspring for the non airbag efini wheel that would have the connector on it, at least I think so.

 

If you indeedf have the Type RB Bathurst X, then it is a 96 version. Type R Bathurst X is the 1995 version. There was a model version swithch from Version 3 to version 4 in 1996 which involved some major changes. Is your car a VIN 400XXX of 300XXX? If it starsts with $4you have a version 4 Type RB Bathurst X. (The brochures are nearly identical). The version 4 cars introduced the airbag momo and the whaletail spoiler. I have a clockspring and Momo airbag wheel from a version 4 1997 Type R. I could share phjotos of the connectors if relevant.

 

My car is a 300000 series chassis number, which would indicate that it's actually a Version 3 in that case.

Looking at the parts diagram I uploaded, I did notice some things I was hoping someone could shed light on.

If you look at the diagram of the clock spring originally shared by J9, there are two 60-253's. Starting with the one above and to the right: My Katakana is rusty, but I believe it essentially says "Rear wiper with" and then "Auto cruse (cruise control I'm guessing?) without"

Then for the 60-253 in the lower portion of the page right below that, it says "Rear Wiper with" "Auto Cruise With" and then "rear wiper without"

I'm not sure which one I need to get. I know my car doesn't have cruise, and does have a rear wiper. so that would point to the top right 60-253, which is what my car has, and is visible in my pictures behind the part I am holding. There's no connection shown there for a horn to plug into at all (on the diagram or on the car when I look.) The two plates I was holding in my hand that have the hacked up black and green wires simply rest against that part. The 66-SP0 looks like it might have a place to plug something in, but what if that is essentially cruise control specific, and has nothing to do with the horn? (it is listed in the box that says with cruise)

So, more rambling here. Moving onto the sheet I uploaded earlier of the factory 1995 non airbag Bathurst-X wheel, it shows 32-780A (the part highlighted in red,) It shows what looks like a plug and wire coming out of it, so I'd assume this would go to the horn, being as how that wheel has no airbag.

So, do I order the 32-780A and see if that can be made to fit with the Non SRS Efini wheel I have, or do I order the 60-253 and its corresponding 66-SP0, and hope those have the connector for the horn??

 

Yep, horn button should have a male spade terminal for the wire.

Those two parts in the first post, are they metallic? Look like bits of plastic with contact cement applied. Couldn't imagine them working too well as an earthing ring if that's the case, don't quite understand what's happening with the pair of wires either.

A 92 half cut we had years ago with an aftermarket momo wheel installed, still had the airbag clockspring installed, using the earth there for the horn, rather than the usual https://www.fuelautotek.com.au/store...andard-profile - never tested it for operation though!

If there was ever airbag stuff, most visible bright orange and blue sensor plugs should be evident under the headlights, at the bonnet catch and the cutout near the brake booster....unless someone in Japan has been particularly conscientious.

 

If you indeed have an enfini (non-momo) non-airbag (non-SRS) wheel, it could be worth a lot of money. Perhaps sell it to fund the rest of your repair.

There is another recent thread on Bathursts, that might shed some light on your situation.

I will dig around some more.

https://www.rx7club.com/3rd-generati...ype-x-1151213/

OK. The other thread is also your thread. (Face palm!)

 

In the other thread, we discussed that you might have the earliest Bathurst, the "blue tint glass version" given you have bins. Did your VIN number verify this?

If you have one of the earliest Bathursts, there may be limited info on what steering wheel came with it.

There are a series of electrical manual updates. I wonder if any would cover the 'blue tint" bathurst?

 

The wheel I bought and fitted to the car is indeed an Efini non airbag, non SRS wheel. I paid a premium for it (it's basically in mint condition.)

The car never had an airbag from the factory, all of the diagrams and visual inspection point to that, plus the lack of vivid colored connectors/airbag clockspring.

What I've posted is basically what is there. the plastic piece on the steering column visible in my earlier pictures behind me holding that plate with the two wires on it. It looks to be made of plastic, and has a copper trace on it that looks like part of what would complete the horn circuit when you push on the horn pad.

However, what I'm holding I'm guessing is a factory 95 Bathurst-X part (I think Nengun called it a contact pad, which, unfortunately, is NLA, its the 82-780A that's highlighted in red.) I can't say for sure if the wiring is factory, maybe the wires are, but it certainly doesn't look like the connector shown in the picture. I don't see why they would use two spade connectors as a factory connector, though. One is green, which I'm assuming is the hot wire, and one is black which I'm assuming is ground/earth. When I removed the momo wheel, I did accidentally have the wires touch and the horn sounded, so I know it was capable of working.

I've re attached the factory diagram below, and circled in green what I've bought from Nengun. Can anyone confirm/deny if those parts will have a plug that will enable me to connect my non airbag/non SRS Efini wheel?I'm assuming it would have to, being that the horn connector for the Bathurst-X is listed in its own diagram, and that's virtually what I'm holding in my hand, and it is not present in the Efini wheel diagram. The parts I ordered circled in green are unique to the Efini wheel, also.

 

The "contact plate" (as its referred to in the diagram, so I'm assuming that's what it is) is very much metallic, with rubber on one piece, which I'm assuming is to prevent contact between one another/closing of the horn circuit?

In the second picture of my first post, the ring I am holding on the right, that entire face is metallic for the most part. That side of that ring mated to the contact surface you see on the car in the background. The other side is entirely black/rubber, and the second ring with the green wire sits on top of that. The horn worked when those were sandwiched together and I accidentally let the exposed areas contact one another, so it did its job even though it wasn't working with the non factory momo wheel.

So I'm hoping by switching out the parts on the car for the parts labeled in green, that will enable me to regain horn functionality with the new wheel. Any ideas?

 

Brian Long"s book on page 158 has a picture of a white Type R Bathhurst. It shows the airbag nashi efini wheel. It also shows rear seats instead of bins. The book mentions that the inital Bathurst was based on the Type r - II, which had bins. Blue glass was the feature of such bathurst. It does not say what sort of steering wheel the Type r- II had.

 

Based on the lack of anything airbag/SRS related, I'm fairly confident in saying it is a non airbag car. In the parts manual, the only MoMo wheel for that year is non airbag as well, and matches the parts found on my car, such as the one with the copper tracing on it that the contact plate attaches to.

I'm just hoping that the parts I ordered, the non momo, non srs/airbag parts, shaded in green, will bolt right up and allow me to plug my non srs/airbag efini wheel into it and have horn functionality.

Does anyone have a non srs/ non airbag car they have pictures of with the steering wheel off? That might be a good indicator.

 

very (very) rare.

 

I didn't think they were that hard to find, honestly. I think I paid ¥50,000 for one that was claimed to be never used. I don't see a scratch or scuff on it, either. I believe you though. Hopefully these parts (whenever nengun gets them to me) will be all I need to mount up and regain my horn functionality. I just wish there were a way to see in the meantime.

 

I have not watched this, but it may be close.

 

It definitely shows that the SRS cars have the clock spring, but unfortunately doesn't show going from the Bathurst-X non SRS to the Efini non SRS. Educational, though.

Worst case I can utilize the contact pad that came on my car that I'm holding in the first two photos I think, but I'm not sure how to wire them up, Green which I'm assuming is + and black I'm assuming is -, but Idk how to make the two wires of that connect to the one wire on the Efini wheel.

Also, side note, anyone have any issues getting the horn pad on an efini wheel to sit flush? Mine will not sit in flush, at all, either the top part wants to sit flush with the 6 o clock part sticking out, or vice versa.
