Trying to keep the engine bay clean... Drilled a hole in the drivers side under the dash and routed them under the fender. I've heard some folks call this a wire tuck. I de-pinned the connectors and ran the wires through one of the heater core gromets. I'll add the alternator wire here also. I'll do something similar on the passenger side but there will be a lot more going on with heater core lines, radiator vent line and eventually the AC lines.
