I own a 1989 SR5 that I have just put a flat deck on. I purchased LED tail lights from NAPA HB9019R that have the 3 wire pig tail. My problem is I am not sure on how to wire them into the harness. I have located all my wire combinations ....brake, signal left and right, running lights, and reverse/backup. If anyone could be of some help here it would be greatly appreciated. A mechanic/ wiring wiz I'm not . Thanks
