Harness for trailer installed on 2020 RTL

[m109anc]

Had the trailer harness installed on my 2020 RTL, plugged up trailer and the lights don't work. I pulled out my 12v tester, had someone press the brake while put the alligator clip on the ground terminal, then touch the other three terminals nothing. I repeated this with the turned signal, running lights, nothing. Any ideas what could be wrong?

It’s not plugged in! Check fuses. Or, the module is defective. Do you know anyone with an F3T that has a trailer module? Unplug yours, plug in theirs. Test trailer. Same module. I’ve done several, no problems. I’m up, call.

If you paid someone to do this, take it back and tell them to do their job. Then have them show you that it is working. Don't accept faulty or shoddy workmanship.

Check the fuse. Refer to the owners manual for the specific fuse. Normally a 10 amp. If it is there and good. I would agree with Stubby. Take it back to the installer and tell them to fix it.
