I keep blowing fuses. The trailer taillight converter has the ground, l and r signal wires, brake and tailight wire. I found the 2 taillight wires, left turn signal and brake wire on the car. thee are 2 wires that I can't get any juice when I test them. This is all done at the connectors behing the little door panel at the rear left taillight in the trunk. Can anyone offer any help?
Thanks,
Jim
