Ok please bare with me Im new to the forum.Ok so I have a 1988 CRX dx with a d15b2 I wanna switch it to mpfi and was wondering if a 1988-1990 Si engine harness would work?I'm going to use the obd0 to obd1 distributor and ecu jumper harness because I have a p28 head I was going to swap on so if anyone could please help thanks.

 

No You cannot use the engine harness only out of a Si. You need to do the wiring because the DX interior harness will NOT plug into a Si engine harness.

Here is all the information you will need to do the swap.

 

Ok thank you I appreciate the info.

 

Also i will Not need the Resistor box because I have a d16z6 head with every thing on it including fuel injectors and I believe there peak and hold not saturated

 

correct except you're slightly confused. peak and hold require a res. box, saturated do not.

 

Ok thanks...
