97 ford ranger trailer wiring hookup?????
Trying to hook up my truck to boat trailer wiring. Bought light setup already wired for trailer with a flat 4 way plug setup. Green-right stop/turn sig, yellow- Left stop/turn sig,
brown for tail lights and white for ground. Located turn signals with light testor.on truck and tail lights. Hooked up ground wire on truck. The stop lights will not work. When brakes applied testor lit up on another wire under my truck. Had nothing to do with the right and left signals .?????????
I am stumped. Can anyone tell me what I am doing wrong please??
