Under my dash, by my fuse block, there is a plug with two wires. A Purple w/White stripe wire and an all White wire. The plug is plugged into another plug with no wires at all coming out of it. It just has a resistor or something similar used as a jumper and it's all taped up. What in the world is it. I've got no key in ignition buzzer or headlight buzzer functioning in my Blazer. Could this be some sort of fix for the buzzers or something? I can't see where it should be plugged in and the guy that I bought the truck from has no idea. Got me scratching my head!

I would if I could find something to plug it into. That's what I was hoping somebody could help me find. Ill try to get a pic of what I'm talking about. (my camera is on the fritz, so I am at it's mercy)
 
How big are the wires?

I thought purple (no stripe IIRC though) and white were the neutral start wires, and what you describe is a way to bypass that.
 
If it's any comfort.....I have exactly the same thing on my '91 :grin:
 
Not sure if this correct or not but I think it would have been plugged into the neutral saety switch on older model chevy's. At a certain point GM stopped using electrical safety switches and built detents in the top of steering columns to stop the rod between the key switch and the actual ignition switch at the bottom of the column. If you take the jumper out your truck should not start. If I'm wrong I'm sure someone will correct me.
 
Interesting idea! If that were the case it could be an easy place for a bit more security, some sort of keyed switch maybe. (as long as it were hidden...every thing helps!)


oops, sorry...hijack!:grin:
