I was wondering if anyone could explain where do the 8 yellow and black wires go to. I know 4 of them go to each injector. But I'm having problems figuring out the other 4. I saw one going to a red wire from the drivers side connector but it wasn't connected to it and was wrapped in heatshrink. I'm just trying to find out what this red wire does and what it connects to. Oh yea its an OBD1 ls harness. Same plug as some of the dizzy wires go to.

 

I believe the 4 are injector ground wires.

PM Turbo-charged, Joe Simpson or ask the same question on d-series.org it may even be a sticky there.

I try to stay away from wiring...

 

4 to the injectors
1 to IACV
1 to Purge cut
1 to O2 sensor
1 +12V Power into the connector for those listed above.

All +12V Power wires and not grounds.

 

Alright....so it's the purge solenoid. Do you happen to know a way to bypass or is there no CEL for it.

 

So i could tap my IAB positive to the 12V+ of the IACV to run my IAB's?

 

Yes.
