Ok so no teg wiring harness? My civic one is still in tact somewhat its just some of the wires have been cut and altered. Is there some place I can go on the web that shows me what each wire goes too? Monicle says its a 2 piece harness for the teg engine. I thought that I would be able to just plug the teg ECU into the civic wiring harness and everything would be ok. I need for someone to help me and not just give me a website because I have been to the following websites handaswap, cspeed, and many others I got by using the search function. Basically I need someone to do me a favor and go into detail telling me how to wire this up. Its a 99 ODB2 LS engine into a 99 Civic EX car.
