Ok as per this thread : http://www.toyota-4runner.org/engin...essories/12315-led-tail-lights-installed.html
I figure the 3 wires coming off the primary wiring harness split to -12v and Grnd. so is the center junction that runs to the other 2 lights the ground or the -12v?
how would any of you wiring guru's go about attaching wire? straight solder or is there a spade/clamp that would work better?
