My truck has been out of commission for a while. I’ve replaced plugs, wires, TPS, MAP, and shift solenoids. It’* in limp mode. I have a spare wire pigtail in the engine bay. Any ideas on where it goes? Brown and black wires, only two. On the passenger side of the block in the same block of wires as the (assumed) fuel injector pigtail and others. I tried posting pictures but it wouldn’t let me. I can personally email pictures of anyone is willing to help.

Send the pictures to my email and I'll post them for you... admin@gmforum.com
