1986 S4 RX7 NA with JDM S4 TII SWAP WIRING??

Its a JDM S4 TII motor with original motor harness in a S4 NA chassis..
I was wondering if anyone knows the rewiring procedures?

I been researching for hours and cant find anything.

So you have the engine, harness, ECU, AFM, and boost sensor?

If so, you just swap over all those items. Should be plug and play.

At least it is with S5.

The JDM engine wiring harness will not fit, cause it's too short.

Damn, I forgot about the JDM part.

You can either rework your S4 NA harness to work, or try your luck at a used, most likely crusty, US Spec S4 TII harness.

Did you read these links:

Other than the basic, swap it all in and see what happens, we'd probably need specifics as to whats going wrong. If you have all the required parts (including the proper length USDM harness) it should be fairly straight forward since you're keeping it S4.
