I have an 85 GSL 12A wiring harness I'm trying to salvage. I want to use teh turn signal/flasher control for my custom harness, yet Chiltons and Haynes manual's don't have the same wiring for an 85. The Haynes comes close with it's 13B 85 GSL-SE as it shows the same plugs, but most of the wiring colors are way off.

Can someone tell me what's what. a simple From and To, or a scan of the manual. I will owe you big time.

Thanks

 

The 84's and 85's are the same. 12A and 13B.



Are you trying to put this in another non-Rex or something?

 

Yes. Trying to use as much of my 85 RX as a donor for a Lotus style autocross car.

The colors don't match in the Haynes manual. If I could only tell what wires are coming from, and going to I'd be fine. Without matching colors I can't tell What terminals A-R correspond to without a lot of work/.

 

Don't waste your time..

The harness Directfreak mentioned would be ideal, but to answer your question I've attached a scan of the '84 factory diagram of the CPU. The next post is the pinout of the connector with wire codes.

 

The connector and wire codes:

 

The photo you posted looks to be right on the money. Now to brush up on wiring schematics.

Thanks, you've been a great help

Yes, if you do not use schematics very often they can be a bit much. But if all you want is the flasher function, you only need to be concerned with three pins :

-Switched 12V at Q. (The cpu diagram shows pin Q coming from the seat belt warning light, but it is an error. They are missing a dot at the proper junction. The IG key line goes to pin Q and the seat belt bulb.)
-Ground at J
-Pin R goes to the turn signal switch center contact.

Thanks FJ

 

You're right on.

I was hoping I could use more than turn singal and door buzzer.

Thanks Again. I was about to chuck this darn thing.
