Re: Old-style 6.2L Glow Plug Controller Question
I just completed a complete reproduction 6.2 harness for a customer and according to my GM schematics, that cavity 2 wire (which is white on mine) is simply labelled as "not used". If you notice, it is indeed cut but its a nice, clean factory cut. No doubt GM uses that pinout connector for other applications is my guess.
