There’s no evidence that the solenoid or valve were ever there, but I don’t know the history of my truck.
It was involved in some kind of front end damage. The insides of the fenders are white, and the front lighting harness was definitely replaced.
The truck was optioned with the compass/temp mirror, but there is no temp sensor. The cavities in the harness connector are vacant, but do not have the rubber plugs in them.
I can’t for the life of me imagine why someone would have taken the effort to remove the pins from the harness, but that’s the case. Maybe said individual also removed the solenoid and clipped the harness near where it enters the firewall. It’s not the easiest area to investigate.
Either way, I think I’m going to go scavenge the parts to add the solenoid and bypass valve.
