Re: 7 pin blade style plug wiring help!
naw, on this one the black wire goes to the convertor on the rv, and on the truck side it goes strait to the battery. i been chacin down a wiring problem. so ive been through all the wires two or three times now on the truck and the rv. i cant get the brake running lights to come on at all and the blinkers and brake lights are some how showing up on the dim side of the two way bulb.. the running light side... i think it may be a ground issue on the trailer side but still not 100% sure.
