So I bought a 91 civic hb without engine or engine harness. I soon after found a wrecked 90 integra, snatched it up and last night got the engine out. Tonight I am working on removing the harness. I just cant seem to find any direct info on where the engine harness seperates from the body harness. I have everything in the engine bay unplugged up to the fire wall but on the other side it goes under the dash. The guy who sold me the ef made it sound like it wasn't **** to remove it. It led me to believe I could get everything in the engine bay and unplug the ecu and fish it through the firewall. Do I need to get everything behind the dash undone or am I overlooking a pigtail that seperates it all. Show me the error of my ways. Also how well will the harness plug into whatever it will need to plug into on the ef? All I seem to get when I search is engine swap procedures that go into great detail except when it comes to this specific detail of the swap. Also pictures are welcomed

 

Although I have no experience with your particular issue, the traditional way of doing this engine swap was to utilize the existing harness (which you apparently don't have) and convert it to MPFI if it was from a DPFI car. I don't recall seeing info on just swapping integra harness, which leads me to believe that interior (main) harness may be different. If I am correct, you will be better off scavenging for DPFI/MPFI Civic/CRX harness and going with that. Someone will correct me if I am wrong.

 

I failed to mention the guy who had it before me had an B18c5 in it. I dont know if that makes any difference because he took the harness also.

 

you need the stock harness for your car. however, since your car effectively has no harness at this point you could go ahead and get a civic/crx si mpfi engine and cabin harness. you can't use the teg harness.

 

Does anyone know a website or something where I could buy a new one. I am trying to avoid buying used stuff on this build or I would go to the junk yard.

 

seriously? no... they're going to be used regardless, unless you go with a full custom milspec harness. is your car a std/dx, or is it an si? that will determine which harness you need to buy.
