alright the car is 90 civic dx hatch back with dpfi i have a sohc zc that is going in the car. i also have a pm6 ecu and crx si motor harness with resistor box.

so my question is do i have to run any wires since im using the si motor harness?
and if so what ones do i run and where to?

thanks matt

 

if you want the new motor to work use the dx intake mani on the zc motor get car working then if u decide u want to wire up to a si get ready to do some BS wiring I CONVERT TO OBD-1 OR 0 after motor is up & runnin cxcivic has masterd this..

 

the zc is obd-0

 

but ur dx is not the same as si wiring thats why u use dx intake obd o - what ever all can work 2- gether ! or obd 2 -3-4 what ever////

 

yo if you got obdo and its ef you got to run two injector wires and if you want v tec its the same number of wires i got a good friend that can help pm me

 

the whole point of putting the zc in is to get ride of the dx manifold.

 

rewire car head to toe with the 90 civic Si wireing if vtec then get conversion harness obd0-1 p28 ecu wire that up walah! pain in the a@# there are many diffrent ways to go bout doin this but this looks the cleanest when done & works nicely...

 

to much work if you ask me. just search for dpfi to mpfi wiring diagram. its not hard run a few extra wires and extend a couple. switc two on teh tps. not bad at all. it will only look as clean as you take the time to hide and make it look good. pulling the whole harness out just means more work if you ask me. ive done few looks harder than it is.

 

im not using the dx wiring harness i have the crx si wire harness.

what the hell are you talking about obd-1 for the car is obd-0 and the motor is obd-0 my ecu is obd-0 crx si engine harness is obd-0 so there for its obd-0 i just need to know what wires i need to run from the distrib. and the resistor box.

 

are you using a complete si harness
