i dont have a clue on how to run my wipers without the harness. i did a TII swap and the TII harness does not have the connectors for the windshield wiper motor.

can i just follow the plug on the n/a harness to where it plugs in inside the car and cut the other wires to the plug and just use the wiper motor wires?

 

the TII harness should have the wiper motor connector, you can get one off a different harness and snake it through along with the engine harness through the firewall. but i still have no idea why yours would not have the wiper harness... all models had it with the engine harness. there is other connectors on that plug, such as the coolant temp wire for the gauge for example so some rewiring will be necessary if someone hacked it off your harness.

 

every TII harness that i have seen did not have them on the harness itself. my rotary head buddy told me that on the stock turbo II rx7's, the wiper harness is installed onto the chassis itself instead of the harness.

 

so you're going to believe your friend over someone who has built several hundred RX7's?

fine by me.

the wiper harness is physically wired in parallel with the engine harness and ECU wiring pins and wrapped up with the same wrap that the engine harness is wrapped in. some of the engine wiring goes to the connector for the wipers, such as i mentioned the coolant temp wire which runs over to the same area as the wiper switch.

 

karak, i am not trying to doubt you at all. i understand that you know alot about the 7's, dont get me wrong. but from the harnesses that i have seen, there is not a connector for the wipers at all. give me a few and i will get some pics posted so you can see what i am talking about.

thanks for the info, though, i appreciate it....

 

no wiper connector........

someone may have hacked it off and retaped the harness. really, it is supposed to be there on all FC model harnesses because all cars had wipers in the same exact location on the chassis so it's not a JDM harness or any other crazy thing.

my suggestion is go dive into a pick a part yard and find an FC harness and grab either the whole harness or just pull out the wiper harness from the main engine harness methodically, there will be other wires that run through the main engine harness that tie into the in cabin side of the connector.

 

i already have an n/a harness with the wiper connector. cant i just take it off the n/a harness and hack off the wires that are not needed for the wiper connector?

 

oh, the harness is stock as can be. i made sure. it hasn't been tampered with at all. its just getting me confused, lol.

 

here is what it should look like on basically all models, the white connectors nearby may be missing as they are for cruise control and sub zero start on early S4 models. there is only 5 wires from the motor connector so you can see how many spare wires run through the engine harness to the engine and to the ECU.

 

yes you can, i just don't have the time to try and figure out which wires were important to keep on the harness connector. i believe(going off of memory) there was only the coolant temp wire, alternator wire and one other which tied the dash harness to the ECU and the rest were for the cruise control/sub zero which may not be necessary if you aren't using it. basically you need to figure out where those 3 wires nearest the blue ones are for.

 

so as i mentioned previously, the wires at the connector in your hand are the only wires need to use my wiper motor? and if so, the opposing connector that they run to, i can cut out all of the other wires? i dont even have the yellow in cabin connector that the wiper motor is supposed to go to, on the TII harness so i can pretty much dismiss all the other wires except the ones for the wiper motor.

 

first you'll have to figure out where the connector went to, there has to be a connector inside the cabin somewhere. i just don't know why it would be missing completely. i have never seen one routed from the driver's side of the car.

 

well, the car is stock s5 n/a so it does have the full setup for the n/a wire harness with the 4 connectors under the passenger side of the dash. i figure if i just remove the wiper motor connector assembly ( black connector, all wires, and yellow connector) it should plug and play without even having to mess with the TII harness at all. how about this:

if it works the way i think it is going to, i will pm you and maybe there could be a thread written about it or something.

the TII harness is a california car harness if that makes a difference.

 

well i have only done a turbo swap into S4's which have different in cabin connectors but i still am scratching my head at the missing wiper connector at both ends.

 

i know, its weird. just one more thing to make everything more difficult

 

If you had read the any of the threads on turbo swaps, you'd find that J-spec EM harnesses DO NOT have the wiper harness integrated. If the harness you're trying to use is J-spec, it's also going to be extra short since it's intended for a RHD car. As I've explained previously, there is no reason you should be messing with a TII harness in the first place when doing a turbo swap. The existing NA harness requires FAR LESS modification. A TII harness requires repinning a number of plug junctions.

 

why would i have to mod the wire harness if i am using a TII ecu, TII wiring harness, and all TII parts? the only thing that does not match up is the wiper setup

 

'cause the EM harness your putting on the car is not a USA harness but a right hand drive jap harness..........which does not have the wiper wires in it . ALL USA EM harness have the wiper wires in that harness ..........which in turn connects to the FRONT harness and then goes to the wiper switch. See online FSM wiring diagrams.

I've no idea why you didn't just use the stk series five non turbo EM harness with all the wires needed. Got me.

 

the stock s5 harness i have is out of an automatic car.

 

I don't remember there being that much differece b/t a automatic and a stick car as far as the EM harness goes.

Both have four injectors in the same location........one boost/pressure sensor in the same place.......a afm in the same place...........a TPS in the same place........water thermosensor in the same place........wiper motor in the same location.............water temp sensor in the same place................CAS in the same location............ACV in the same location........ Relief, switching, FPR solenoids in the same area...........no 6 port solenoid for a turbo car so that's a difference...............no turbo duty solenoid on a non turbo harness for your turbo car.........no VDI solenoid on the turbo engine.......no knock sensor wire on a non turbo car (who cares?).........both have a BAC............both have a air intake temp sensor........... so I don't see much of anything to worry about. There's noting special about a car having a manual vs a automatic transmission. The automatich is controlled thru another computer, not the ECU.

No interlock switch for the starter on a automatic but that's not EM harness related anyway.

So I'm saying I would not worry about it having a automatic EM harness in the car vs a manual transmisson harness.

That's just my thoughts on this and thats that.

 

you can untape and separate the harness and be left with the wiper harness.
This is how my vert is, I also have standalone wiring for everything else on the engine so I had no use for anything else BUT the wiper harness.

For some reason I had thought that TIIs had the wiper harness in the body harness, and NA cars had it with the engine harness, but I have not built HUNDREDS of RX7s so I may not be the best authority on that.

 

Jpg attached showing what harness has the wiper motor on a series five. Series four is the same. Both turbo and non turbo cars. All is for USA versions of the wiring, not for Japan which is different 'cause they drive on the wrong side of the car.

 

Use your NA harness. The only mods you have to do is replace two of the solenoids plugs one will go to your boost controller and the other to your knock sensor. Just print the NA and TII wiring diagrams and it's super easy to do. That's the route that I took while doing my S5 TII swap.
