Re: headlight switch short? and console connector wiring diagram need
Basically, im installing efi and went to wire in my 12v key source to the computer. just for kicks, i wanted to confirm that i had the same wire that i had connected to the 12V ign at the fuse panel. if its the correct wire (12V switch) then i figured that id have open resistance to the ground. well, i didnt. i had just a few ohms.
so, ive since traced the low resistance to the gray wire in the under dash console connector and im trying to figure out where that goes and how its wired. i know that gray seems like its convention for the lighting, so i figured id try the healight switch to see if anything happens there.
so that brings me to my post above. it seems like no matter what position the switch is in (off, on, park), there is very little resistance to ground. and i believe that theres a problem with that. there shouldnt be anything that when the car is off/at rest/doors closed that should provide such an easy path to ground.
so, i was wondering if you guys could confirm that your cars act the same or different and, if possible, provide a diagram of how the underdasdh console connector wires in to the rest of the under dash wiring, so i could trace it out.
Does that make sense? I may have absolutely nothing to worry about, but i want to know why that gray wire doesnt see much more resistance...
