If you plug that harness in and test the red wire, you wont get the switched 12v...because that harness is basically for a 97-03. Everything else should match up, except for the harness that that one plugs into doesnt have a switched 12v in it. So you just run your own. If they didnt include it in the kit, just go to autozone or any parts store (Walmart probably carry that wire) and pick up a 5 ft roll of primary cable.
