Okay, next question on the new to me 04 W900 daycab. So I pulled the radio out of the dash. It is hooked to speakers in the headliner. I am replacing the deck and find another paccar connector labeled speakers. Does anyone have any idea where the second set of speaker wires might be hidden? Thanks everyone for all the help so far. Hopefully I can return the favor.
Might just be wiring for speakers in the sleeper. Most wiring harnesses are generic across the same model and not specific to each individual truck so they'd just be plugged off on the other end since its a daycab.
I had a chance to pull the glove box and look closer at the wires. They are marked sleeper speakers. Anyone know where the harness that goes from the cab to the sleeper is run?
