I had everything setup correctly with my original radio, the problem came in with the loan radio. But not to worry, busy fixing the problem. This is the first time actually working on a truck so it is taking some time. Lots of fun, just a bit nerv wrecking sometimes. I just don't have enough light in my "workshop" so i am fitting stronger lights and a spotlight that i have mounted on a retractable shaving mirror. Funny how you start looking at all types of solutions for things when you actually need to focus on getting the truck fixed.
