People say that an SI harness WILL NOT work on a HF chassis
You have to get an HF harness...for a HF.....

 

Kay nevermind.....my frined came over and we tested contiuity between the ecu and the driverside engine plug to see which wires went were, and it turns out the harness is all wrong....Im getting grounds where i should have power, and power where i should get ground.....the harness is totally fukced.......Im soooooo glad I ordered an HF harness....for an HF car, I should've done that in the first place.....The wires didnt match....from the ECU (A15) to the resistor box plug...which is Red\black....that goes to the big plug which is supposed to be Red\black also.....was Blue on the other side...and red\black on that side was going to injector ground.....WTF! Its a mess......he told me i could rewire it, but ---- it i jus got another harness

 

well i fixed my car.....thank GOD!!!!!!!!!!!!!!!
