It is a 4 pin plug that should have a relay plugging into it, it appears anyway. White plug near the 4 ac relays(still have the 4 ac relays hooked up so its not them I hope). Wire colors are as follows   Blue/white Blue/white Blue Black   I traced the first 3 going into the car through the drivers side big harness. Black looks like it nay go to ground.   Car has ac and analog gauges. I checked the service manual and I am still scratching my head.

Anybody going to be at the west town mall Sunday morning... Might make it. If I do I'll snap a few pics

I've got an authentic HKS cam in one of my cars and the HKS cam grind spec.   Who's interested in an HKS cam GP?

I have 4 gauges I need to run to setup on my dash somewhere.   My wideband, water temp, oil pressure, and boost gauge....I'd like to drill one hole and hope for easy access. Where is the best place to drill a hole and add a grommet and run all these together?
