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.

 

plug NA harness into TII ecu, plug engine harness into dash harness. thanks i'll be here all semester.

later you can use the VDI wire as the knock sensor wire (same pin on the ECU between na and TII)

 

Jacob, fix your signature... or it will be deleted.

You can have 10 lines without a picture, but 15 lines and a picture is way way too much.

 

thanks for contributing to the thread mark you're just mad cause i beat you to it :x

 

use the engine side harness from the t2, and the interior passenger side harness from the NA. yer done,.

 

Wha I did was use the JDM harness and stretch it to the passenger side as much as possible. Then you have to splice new wires in to the plug that connect to the dash harness. It aint that hard as I have pictures. If you wana do it this way just PM me. Pics are quite big too.

So what I am actually doing is just making longer wires of the JDM harness and connecting it to the NA chassis harness? Doesn't seem that bad. The coil problem I solved it, stupid mechanic got me confused. But the thing with my JDM harness, is that it is cut. Is that a problem? I dont noe if they cut, I was thinking jus rewiring them. But I'll get more info if possible. And pic would help, please. Thanks again.

 

OK so you could splice in the NA harness with the turbo narness or you could take out the jdm harness and use the NA, the only thing would be to know what wires are extra and use those for the boost controler switch. All the sensor are preaty much the same ont he NA and turbo engines.

 

Hey you live in fresno. My lil brother is starting school at Fresno state this monday. I live in watsonville CA, that's like 3 hours away. I might bisit my brother in like two weeks, so I might go and help you for a bit.

 

O yhea that is all for the engine harness. All that is left is to plug them in. youl have to sauter the transsmission wires too.
