Can anyone in readerland post a pic of how the wiring for the turn signal/ignition switch, and the delay wiper module and wiring is routed? Specifically, how was the harness clipped in place? Where did the delay module mount? Was the wiring routed above the steering column? Or over the brake pedal mount? Unfortunately, I have slept a lot since I removed all this, and the way the harness wants to lay in the cab isn’t providing any clues. Thanks!!!

I figured that out. I have 5 of those delay modules I removed from donor trucks, every one of them had broken mounting tabs and were hanging by the wires. Guess that’s why zip strips were invented!!!

it's a 77 that didn't originally have a delay. The delay and wipers motor came from a later model donor 85-91 and required some rewiring.
