i'm putting z6 in my 91 crx si. do i use the si harn. or do i use the new one. will the new one plug in to my engine bay harn.

 

You modify the existing harness on the engine bay side, and you use a converter harness that plugs into your stock harness on the ECU side.

 

 

so what do i need to get i thought the obd0-1 harn. you bought was for the ecu part?

 

Keep your stock harness, plug in the OBD0-to-OBD1 harness. Extend the appropriate wires and you are basically done. In the sig

yeah w/ an obd1 motor all you have to do is extent wires off your existing obd0 engine harness. its cake

 

yeah, you just gotta do stuff like change the distributor plugs, add the 4 wire 02 sensor, extend the MAP sensor wires, change injectors, remove the injector resister, stuff like that.

 

You actually do not have to change the injector clips, or injectors, or remove the resisitor box...those are optional goodies.

 

so when i get the harn. i still need to get another for the p28 ecu to plug in.

 

what do you mean when you say "extend" the wires?

 

Exactly what I said... Splice in a length of wire to make the plugs reach.

Blown90Hatch... you don't have to take out the injector resister???? I thought you had to because of the different voltage of the newer injectors! Not to mention that my stock injector clips would not fit on the new injectors.

You can run the OBD0 injectors as long as you keep the resistor box. So if you want to, just keep the OBD0 injectors and resistor box, or change to OBD1 clips, injectors and ditch the resistor box all together.
