My 1987 Silverado Crew Cab Dually 3500 has this pictured connector dangling down behind the dash. I can't find a connector to attach it to. Tried checking wiring diagrams, but can't seem to find it. Anyone out there know where it belongs? Thank you.

Doesn’t appear factory, colors could be from the neutral switch? Maybe a for a kill switch? I would start by testing, start with ignition on, off.…See if it’s connected to the fuse box?

Good info! Front panel connectors are nice and easy on a test bench, but I hate putting them on when I've got the board in the case already, but not really an option!

that looks like the brake switch connector for the torque converter clutch. If the truck has a TH400, that would explain why it was t plug into anything.
