Have mostly completed the wiring upgrade for the headlights. The relays are in place and the wires are run to the radiator support. 10g from the alternator BATT terminal, through a 30 amp breaker, then 12g to the bulbs. The factory has spade connectors in rubber sockets going through the radiator support sheet metal. I think these are going to prove to be unreliable, so may replace them with weatherpack or bullet connectors and a grommet. The portion of the wiring from the radiator support to the headlamps is still original so I will want to change that section out when I replace the current T3 bulbs with the new Hellas that are coming.
