Hey so i have a DOHC ZC in my 91 Si and im wondering what i should do about a wiring harness??? I have the right harness for it, however the problem is that the harness looks all choppy and its throwing me codes...... Is it possible to buy a stock si harness and swap over all the pigtails?

ZC harness and your si harness are identical. Just use your stock harness.

guess you didnt read that OP's stock harness looks all F*****d up and is throwing codes

your best bet is to try fixing your current harness and make it look good

and yes you can buy a stock si harness and swap pigtails if needed, sometimes they will pop up in the marketplace section or ebay

DOHC ZC uses a complete different dizzy and cam sensor plug for OBD0. If your getting codes for the dizzy you need to swap the wires around. What are the codes you are getting. A lot of codes does not help.

He said he had the right harness. He didn't mention if he reused his or used the one that probably came with the engine. Either way they are the same. Just have to re-pin 2 wires for the dizzy and cam sensor and that's it.

Here's a write-up from the FAQ section at the top of the ef page http://www.phatwhippincrx.20m.com/photo6.html

codes 6, 10, and 20. Being AIT Coolant temp and ELD. I have a new 89 Integ dizzy that i just put on! The car was running fine aside from the codes it showed and then we took off the harness, tried another one which didnt work cause of different pigtails and so we put the other one back on and now it turns on but doesnt want to crank or prime.... No its not the main relay i tried a few which are pretty much new. Good Soder joints and everything
