Beast17

Took it to the dealer no power to connector not a fuse or relay. Something between firewall and rear of vehicle they are still going through it but will be under warranty

My 17 NV3500SL has factory installed hitch and wiring harness. When hooked up to trailer right turn signal is not working. Already did trouble shooting on trailer and it is definitely the NV. I Checked fuses under hood and they were good. Any other fuses or relays I need to look for where are they? Or any other ideas?
