Trailer Plug Issues

Can someone point me to a thread that might answer my question? I'm sure it's already on here but I need help finding it. I have a 2001 F150. I put led's in the tail lights the last time one burned out. Yesterday I put in an NP27 flasher to correct the hyperflash, and today my trailer turn signals are not getting power. The trailer taillights burn, but the signals won't light. My best guess right now is that it's the flasher relay, but I want to be sure before I go digging for it again.

You are probably correct on the flasher, put the old one in and see if that affects the problem. I looked in the diagrams, your truck does use the same flasher for the truck and the trailer.
