No trailer lights after hitch swap

[BruceinCT]

I recently swapped my factory class 2 hitch for a used factory class 3 hitch with 7 way rv plug and harness. Everything went well and the plug for the harness seemed to connect well. But I have no trailer lights at all now. Does anybody know what might have gone wrong?

A blown fuse perhaps?

I'm going to check it out today. Not sure which fuse it would be. I was just wondering if anyone else had it happen to them also.

I took a look at it. Before I installed the hitch I painted the frame and hitch. It seems that there was no ground from the frame to the hitch. I backed out a couple bolts, scuffed the frame and bolt faces and hopefully we'll be good to go.

Bruce I don't know why I didn't remember that, I had the same thing happen on another brand truck when I put a fresh hitch on. Best wishes.
