car is a 90 sx mpfi swap wit complete si wiring I CANT FIGURE OUT WHERE A COUPLE CLIPS GO!!! any diagrams or info on wire swap will be greatful thanks in advance guys takecare

 

When you say "complete Si wiring", do you mean you are useing the Si engine harness? If you are then I suggest you put the DX harness back on and add the wires you need for the MPFI swap. It is always best to use the harness that came in the car and add any wires you need to make the new motor work.

 

no i am using the complete si wiring interior and engine the whole thing

 

You changed out the entire wire harness in the car and under the hood


First of all WHY!!!!
Second, I hope you are not surprised that you are having problems.
Third, get a Helms manuel, you are going to need it

 

first,cause i want it clean
second,im not surprised one bit that theres problems especially problems no ones heard of
