Harness swapping? ***NEW INFO NEED MORE HELP***
 

I have a 90 crx SI and I am swapping in a 90 B18A from a DA. The harness look the same from what I remember. Can I leave the harness on the B and plug it in? I usually use the harness in the car but from what I remember its the same. The car and the engine are in 2 different places so I figured I would just ask.

Thanks
David

Nope keep the si harness unless you like cel's

What is pinned different if you off the top of your head? I will just use the SI harness.

Re: Harness swapping?
 

All I know is whenever I switched harness on cars etc I got codes and that was the same chassis but different years for example 88 si harness in 91 si and so forth.


That was enough for me why learn something that is wrong get my drift. Better things to use my brain for.

Well I just took the A6 out of the crx. It seems I would have to use the integra harness. The integra uses 2 vacuum solenoids mounted to the firewall and a 4 wire plug. The crx uses 1 solenoid on the firewall and one mounted to the intake manifold. See the issue? The 2, 2 wire plugs will not work with the 4 wire plug for the solenoids for the B18A. So what are my options?

Thanks
David.

How can I just leave them unplugged? won't I get a CEL?

Um sounds like the map your talking about. You use your stock si map. Trust me I have done my share of ls swaps in crx's you use the stock si hatness

No not the map. The crx has one solenoid mounted where the map is. The integra has 2 solenoids mounted where the map is.
