I am looking all over the internet for a labeled picture of a b20b engine wiring harness, or a video of it that shows each plug and what it plugs into. I have taken my 89 wiring harness off of my b20b and labeled everything that I took off, but there are extra connectors and I don't know where they go, or if they can be eliminated. When I got the engine and harness, the harness was so hacked up, a mechanic named it "Frankenstien".

Please, someone, make a video and say something like, "This plug goes into the dash harness plug that goes through the firewall on the passenger's side. This plug goes to the ?? sensor right here.. This female connector attaches to this ?? here. I'm sure there would be a big demand for such a video. I can't be the only one with this problem. Shoot. Maybe you could do it with the other wiring harnesses and become a youtube sensation.
Just do the 89 Integra LS first please and message me. Thank you.

 

Why don't you just post pictures of what you are having a hard time figuring out with what is already plugged in and we can respond? The reason I say that is because most plugs fit multiple sensors and depending on where it is on the engine harness will change what it plugs in to.

For instance, depending on car, the IACV, IAT, CTS, and radiator fan switch all use the same plug. (may be one I am forgetting but I don't think so). Just like the TPS and MAP can be swapped.

You might just be better off doing it the old fashioned way with a digital multi-meter and pinning the ones in question out. It really isn't that bad and is rather quick to do.

 

I'll do that, thanks. The only hard part is that I have now redone the wiring harness, and there were sooooooo many cut, and connected wires that I doubt the harness is even identifiable any more. I think the ones that I have that are extra can be identified though. So I will take a picture, or make a video of them.
