Update on my issue:
With the help of a friend who spent a few years working as a mechanic at freighter we narrowed down the problem to be the emergency dash valve. I ordered a new one and installed it today. Lo and behold I was able to release the parking brakes AND have my parking brake light turn off. I also learned that I need another new brake canister now that I’m getting air to it.
Thanks everyone for all the input. Even the remarks on the questionable welds to the frame😂. If yall really wanna rag on my truck I can post some more pictures.
next on my list is to get the wiring for the tail lights and trailer lights in working order.
