I'm wiring retarded... Can you tell me if this would work? Assuming that everything below is correct.
First off my tag lights are not wired at all, there are 2 wires running to each bulb socket thingy (a blue with white stripe and a black with white stripe). They get spliced together at one point and come out at 2 wires (same colors listed above).
So assuming that one of those wires is a ground and the other is a power source can I wire these little lamps into a hot wire on the trailer harness?
If I was to do this my thinking was that I would ground the black wire with the white strip (again I'm assuming this is the ground wire) and use another piece of wire to run to the trailer harness and test it till I find the hot wire.
So after all my assumptions can anyone tell me if in theory this would work?
