Hey real quck question. i am dropping in a z6 into my 93 cx. I have the Z6 engine harness, p28, and Stock cx ecu harness (what ever you call the harness that goes through the firewall) Do i need to add wires to my harness, and if so what ones and where do they pin into the ecu at? Eh, maybe it wasnt as quick as i hoped, but i need a quick response. thanks.
