Was trying to hook up trailer wires for a trailer. I put new wires on the trailer, kept the lights. I went to U-Haul to get the wire for the van and was going to wire it myself. I had it at one point on the van working then hooked it to the trailer and nothing. The problem now is my left blinker blinks fast when turned in that direction. Checked mini fuses not sure about the bigger ones. Any help would be great. Thanks

The problem could be in the wiring, recheck the wiring on the trailer, check the ground between the truck and the trailer. Check the light on the left side bulb on the trailer, I find that on some cars if a bulb goes bad the blinker flashes faster.
