large blue plug = auto harness

smaller blue plu = manual harness

thanks

actually...just trying to see how many technical questions really get answered on this forum anymore...


So far I have realized no one know **** about the wiring on the rx7

Dougie_fresh_007

hmmm.... i couldnt tell ya i jus know they are all diff sizes so i dont get um mixed up

It is definitely one of life's great mysteries. If you want to know individual pinouts that information is in the FSM. I never really notice much of a logical grouping of functionality per plug but maybe I just missed something.

Lets try it another way.

Which plug is the x-05 plug? Is is that huge one on the auto front harness. On the manual engine harness, it is a smaller blue connector.

Thanks

cover8

Thanks for the help from those that responded. Unfortunately, doesnt seem to be anyone know jack schitt about the car anymore.
The answer, after looking at the schematic for about three hours last night:

x-05 is the blue connector 10 wires from the engine harness. It connects the engine harness (called EM on the FSM) to the front harness on the car.

On the auto the x-05 is HUGE connector with many more wires than the manual x-05.

The x-07 connector is the 12 wire white clip from the manual harness (EM) and it connects the EM harness to the dash harness (the clip high into the dash/firewall area).

The x-07 connector on the auto is 15 wire and bigger than the manual x-07.

The part number for the harness that provides and intermediary between the EM harness and the F and Dash harness have distinct part numbers because the connector are different at the EM interface.

auto #: N3Z2-18-051
MANUAL # N3Z1 - 18 -051

Just to give those that are doing their own work on their cars some help....too bad this forum is full of dumass & dumass instead of technically knowledgeable people.

hey i feel ya one of the moderators jus totally knocked my post and i jus needed to know how to tune my ignition for my trailing plugs to retard 30 degres.... im sorry i couldnt help ya tho... i know more mechanical applications.... but this does make me wanna look into this stuff

it's a conspiracy. itried to post a thread a while back and got banned b/c it posted witout even blinking at www.nopistons.com and when i tried just to post a thread with some jarble....it went through perfect. so i edited it it with a link to nopistons. ==intsant bannage. now i'm trying to post some pics for the new info concerning the 3bar map sensor when running high boost - what do you think? can't post ****

If I remember the thread correctly, it wasn't the link that got you banned. I believe it was the message content (namely something along the lines of "this forum sucks, go here instead").

Links to NoPistons have never caused people to be banned. I'm not the one who did the banning and I don't own the forum. However, if I did own the forum, comments like that would tend to tick me off as well.

So, there is no conspiracy. I don't believe you can attach files to messages in the forum right now. It's not set just on your account. Just use one of the free picture hosting sites like ImageStation until the forum can move to a cluster setup.

Hey Cover8:

While you're at it, would you by any chance know which is the RPM signal wire on the harness? I posted this question before but nobody responded. Thanks

The rpm signal can be picked up in the diagnosis connector, and is generated from the ECU reading the crank angle sensor. I do not know what test point it is, sorry .

Does anybody know the difference between an 8 bit harness and a 16 bit harness? I have a '92 FD3S (JDM) with an auto and am trying to install a manual transmission. I'll need a wire harness and ECU and I came across a 16 bit harness in new condition for about $50. Will this work with my FD and any manual transmission ECU or is it specific to certain years/models? Thanks for any help and please limit the flames because I'll admit I'm a noob right here and now.

Spoolin7N

i'm gonna be honest and to the point. i can remember the thread correctly, you my friend are probably hazey. let me refresh your memory since i can't even find the thread in my old archives.

i sat in front of my computer for hours one day trying to post a thread about some engine parts i needed to sell. after typing the new thread out 8 times with nothing but a 'sending request to rx7club.com message' for at least 5 minutes each, it would come back and say connection was refused. if you saw the original thread, you would have seen my frustrations in the fact of having to type all the parts and the mazda oem numbers to inform the potential customers that i was on the up and up supplying pics and all. but wait, you never got to see that thread did you? no- because of the forum. the same one that is having difficulty with uploading images right now(or earlier for the 3bar sensor thread of mine in the single section and the fact that a lot of times, when i am trying to find info, it gives the same 'connection refused message.') and the same one back then that didn't allow me to post my thread after the eighth try. after posting it at nopistons, i came back to try and post a new thread again and just typed random **** and it posted. i went back and edited it to something of this effect:

"******* figures. i've been trying to post a thread all ******* day about some engine internals i have for sale for an FD and this place won't ******* let me do ****. tried posting a thread 8 god damn different times and nothing. not a ******* thing. this place sucks.

go here"

'here' was my link to the thread at nopistons. it wasn't meant as a dorogatory(sp?) statement telling people to go there b/c this place was ****, it was a statement of frustration with a link to the thread that i tried 8 times to post here and was not able to do. i know this place is a large well of valuable info that i count on and contribute to when i am able, but it was erking my last nerve and i lashed out. i am sorry and have apologized to a lot of people and would like to have my old ID reinstated. if you have any pull, please confer with riceracing or jason, badog, jeff48, rotorbrain or a few others who would be willing to put there neck on the line for an innocent guy who was wrongfully accused of being a ship jumping traitor

thank you for hearing me out. i'm sorry for yelling.....and the long post. and if this sounds mean or offensive or disrespectful, mahjik, i don't have that intention. i just wanted you to know my side

Spoolin7N

i sent a message to boostd7 as well. i informed him of my problem, but maybe not to this extent. if you could pass this along to him and get this cleared up, i would be most thankful.

roy

Merciless

have u heard of technical difficulty?
also, if you went through that much of reposting and loosing your input everytime, didn't u learned anythign by the 3rd time? copy the stuff you type in case something happens again?

if you want that old ID to be reinstated, please act civil..shiet happens in this world man....PM me...

bureau_c

What exactly do you mean by "16-bit harness?" If you mean a harness to the 16-bit ECU in the newer JDM cars, I would be shocked if it fit the 8-bit ECU.

jds

Chrisurfer

The 16 bit won't work with the older, but they didn't change to 16 bit until 99 if i'm not mistaken. I redid my 93 fd with a jdm halfcut and the harness (slight mods) works, it was from a 96 efini model.

Engberg

What is this, the lets bitch about rx7club.com thread disguissed as an ECU question!? More people are willing to help if you don't act like a chode and say "lets see if anyone actually knows anything on this forum"

rxrotary2_7

it is IG-

rxrotary2_7

exactly.
its funny how people complain when its down and say the other forum is so much better. thats great... i am not knocking the other forum, but look at how many people are online at any given time. what 27? 16? if that site had the problems this one had with the amount of users it currently has, i would think that one is a POS... oh and wow, you can post nudity there. big deal, i dont log on a car forum to view ****. maybe thats just me though.
sure there are problems with each website, but ITS FREE!!! why complain so much about it? why try to post your FS stuff here 8 times if the other site is so great?! why complain that you got banned? you should be thankfull you got banned from this site so you could go to the *better* one that doesnt go down instead of creating a new acount trying to prove something and complaining about it, and then starting threads saying *HELP!! i got banned* whats a guys gota do to get back on?

cover8

Actually, that is not what is said. I was being sarcastic...since I have posted in depth threads on this subject. I wondered, in frustration of course, if anyone really answers technical questions anymore...truth is very few do...unless it is a "BOV" thread!

That's not fair for the forum or quite true.

People learn what they need to learn because of problems or modifications they are doing. People post boost problem resolutions because they have solved them in the past. People post about BOV's because they have had experience with them in the past. Do you think you would have ever search for this information if you weren't doing the conversion?

I would wager that VERY few people have needed to dive into the ECU wiring too deep. Even at that, there are less than a handful of people on the forum who have done an auto-to-manual conversion without letting a shop do it for them. IMO, if you want to be mad at someone for not helping you out, be mad at those people for not posting.

I would imagine that even the older pioneers of the early FD days didn't call everyone else useless because they had to figure something out on their own. They shared their ideas and findings to help others.

rxrotary2_7

very well put

cover8

I was being sarcastic. I realize that I am breaking new ground. There have been a few folks (Art, Jeff and MCF among others) who have spent alot of time helping me. But please dont make more of it than it is...simply venting thats all. Dollars are way into the thousands and car wont even turn over...hope for a response on the forum and I read (just joking) BOV threads!

Despite some popular views, the conversion is very involved and expensive. The mechanical part is just the "tip" of the proverbial iceberg. Electrical conversion is complex and still unresolved issue in my case.

But I promise, unlike most threads on this forum that end without conclusion, I will finalize my findings.

Sounds good. Now hurry up and get that car back on the road. We are finally getting some sun again!
