Review on 🔌 CUSTOM 4-Pin Trailer Wiring Harness Vehicle-Side by CURT - Compatible with Chevrolet Express, GMC Savana 1500, 2500, 3500 by Maurice Jimenez

I bought this for a Chevy Express van to convert a single car turn signal/brake light to a trailer light. I tried 2 of these and none worked. Sometimes the left turn worked, sometimes the right turn, sometimes nothing at all. I thought it would be a simpler plug and play option but the two I got didn't work. I bought the kit that needed to be hooked up at a farm and fleet store and now it works great. I used the splice harness from this splice kit so I didn't have to cut the factory harness as well. The only positive point that is not disappointing is that it was delivered quickly.
