ok i m trying to make a strange thig work here lol

i have a 1989 base n/a rx7 and i just bought a s5 tII almost complete motor but no elcetronics( boost sensor,ecu wiring harness etc.) but i just bought a couple days ago was a 1987 tII parts car. A friend and i are swaping all the s4 components onto my new s5 motor (saving the s4 for later lol) im using a 1987 tII wiring harness in my 1989 s5 base. now is where it gets tricky i need to find a good wiring diagram so i can cut and splice my tII harness to fit in my n/a car its the 2 connectors that are up inside my dash that will have to be plugged in . if anyone could please help mefind a diagram or somthing would be amazing awesome



thanks

Umm..sorry i can't help you..free bump..let me tell you this. I really think you'd be better of buying used s5 components instead of the frankenstien project you are attempting.

 

But if you're crazy enough to try, you'll not get any better wiring diagrams than from the FSM, availble at www.iluvmyrx7.com

I'd go to an engine mangement system for what you're doing, though...

 

I assume you're using the TII injectors & fuel pump.

I have a link to a copy of the manuals in my sig below.
Download the S5 fuel & emissions section & print what you need.
