Both Peter Jun a.k.a. Junpower and I have searched, but have found no info that we needed.

Hi, I am doing a NA-to-TII conversion on my 91 NA Coupe. I got all the parts necessary for the swap. Its just the wiring that gets me confused. Is there some sort of diagram that anyone has? I was told I could use the NA harness and plug everything back in. I was also told there are extra connectors to cut off from JDM harness to add to NA harness. I need to know exactly what these two connectors are. I also need to know how exactly in detail how to use the NA harness. I don't wanna hear no answers like "SEARCH" or "Use the NA harness and rewire" that doesnt help me much, I need to know how to and which ones. If those are your answers, then don't bother being a lowlife and replying in this thread just to hate. I need serious and helpful people here.And prefer people that have actually done a Na-to-TII conversion. And the FAQ on the archives dont tell me nothin bout which wires to use. I would really appreaciate it if someone could help me. Please. Thanks in advance.

 

That's one thing that kinda pisses me off about the FSMs... they don't mention the wiring harness at all, just the ECU pin codes...

Sorry couldn't be of much help, but here's a free bump for ya!

 

Hmm not sure really.
I've only done the swap in a S4.

Take a look at the Jspec vs the NA one.
Look at the plugs and see what is missing.

 

What do you mean, Red Neck? The harness code is in parenthesis right beside (or under) the color code for each wire in the FSM wiring manual...Can't get any easier than that...PM me if you need some electrical tutelage
