I have a B18A1 OBD1 for a 93 Integra (I was told) and I am trying to wire it into my 89 CRX. I have everything figured out except I don't know what this plug hooks up too.



Anyone know?

 

You have the throttle body and IACV all plugged in as well? Because it looks like its one of those, those are really all it COULD go to.

 

fan temperature control

 

yup fan switch

 

Thanks guys that really helped a lot. I figured out I had something hooked up wrong but now I have a different plug I am unsure about. This has a white with a green stripe and a black wire coming off it and I tried to trace it back to the ECU to see what it was for but it doesn't make it back to it unless the wire changes colors somewhere after the engine harness. The only thing I could find was that it was for "ALT C alternator Wht/Grn, n/a" but that slot (A16) on the engine harness isn't even filled so I'm confused. Here is a picture of what plug I am talking about, knowing the support on this forum I'm sure you guys know it off the top of your head. Thanks in advance.
