I just received my dash kit for my 06 Ram. It is for a single din. I purchased it off of Ebay and it came with a wiring harness. All I have to do is match my wires from this harness to my aftermarket unit's wires. I am confused about something. The harness that plugs into the factory wiring has 2 constants and 2 grounds. The aftermarket unit has only 1 of each. Do I just cap off the spares and not use them?
