Hey guys, working through a 1983 K10 Scottsdale. I’m needing power to the cig lighter which I have found to be completely unwired. I know the ground is designed to be achieved thru the mount and dash, but I don’t know where my + 12vdc is supposed to come from. There is an orange wire that has been stripped back and is twisted onto the outer casing....should that have been my +12 that someone wired incorrectly? Is it supposed to be switched or constant? Thanks in advance
