Once I’d figured out that it was going to work like I hoped it would, it was time to solder the joint and heat shrink it. Always heat the work (editor’s note: In this case, the wire) and not the solder. Once that was done, I moved on to the lighting issue. The Quadratec adapter harness came with a CANbus interface box, and I tapped into all these wires between the box and the new radio. I’m not sure if any of this would work if you tried to do it on the other side of the box, but the sPOD people tell me it’s a really bad idea to even try.
