I have a few connections from the engine harness that I need to verify on where they connect to the UIM. If anyone can help, I'd apprecate it.

1 - ISC (Idle Speed Control) black/white stripe & blue/green stripe (B1-35)
2 - AWS (Accel Warmup Solenoid) black/white stripe & brown/yellow stripe (B1-36)
3 - IAT (Intake Air Temp) green & brown/black stripe (B1-42)
4 - Oxygen Sensor black (B1-47)

 

All of them should only plug in to the proper sensor. I believe they're keyed so you can't plug them in wrong.

yes they are keyed so you cant mix them up

 

i only can find 3 of the connectons on the UIM. where does the oxegen sensor connect?

 

O2 sensor on the downpipe.

 

thanks Mahjik...i took the uim for months and now paying the price on where everything goes...

 

ooo i was just looking for this tonite! so the plug that goes to the o2 sensor is the lil one that has like a ground wire next to it right?

i know it fits the o2 cause i tried it but wasnt 100% sure if this was the right plug

 

All of the connectors are keyed, except for two that are the same. The only difference is the wiring color and the color code on the inside of the connector itself. The one for the IAT is yellow on the inside and the one for the AWS solenoid is orange on the inside, but the connectors themselves ARE the same.

As for the O2 sensor connector, well.......that one should be pretty obvious. It's the only one that size and there is only one wire that will plug into that connector.
