PLEASE HELP!!!! My truck is a 05 Tacoma prerunner double cab and the green parking light wire has a dead short in it. I cut the wire going into the firewall and wires for the front two lights check good but from behind steering whee to the rear lights I get continuity to ground on green wire. I then cut wire under driver door to help eliminate the rear wire but it checks continuity to ground on both sides of the cut. Where do I go from here any suggestions?
