I have a 99 championtrailer. I added 2 more running lights under the step-up on the trailer. I drilled a hole and a sandel through the bare metaland mounted the light, I spliced the hot wire into thhe hot lead goiong to the original running lights. I cecked all connections and trailer hook-up.
I have brake and turn signals, but no running.
Can't figure it out, need help any suggestions?
