Oh ok so it's wired directly to the battery , as you mentioned, a power drain. Reconnecting the wiring now and it worked! but I'm hoping it wont kill my battery. I feel like previous owner disconnected because the van was parked forever?
This is my first GMC van. When I bought it the owner said there was a CB radio in the van that got deleted and now the radio is "unplugged". It's a nice pioneer radio and speaker system that I really want to use but I can't figure out where to start to try and get it working. Need help! Thanks!
