my under hood decal says the est is a tan wire with black stripe, sounds easy right? even says it branches from the power strip on my firewall under the dust cover. well there isn't any tan w/black wires coming from it so i figure it must be in the 60 wire bundle soemwhere. any ideas where to start looking so i don't have to take the wire loom off all my wires hunting for it. thanks

i found it, sort of where they said but not quite and it was under some black tape.

 

Ahhh, the joys of GM wiring Glad you figured it out though!

 

I was just about to run out to my sis' 1500K 4.3 when I read your first post, but then you got it.....
