Trailer Light Issues, Intro

What's up, TW? Long time listener, finally found a Taco for myself. 2001 Lunar Mist TRD Xtracab, pretty pumped! I've been looking for quite some time, and found a one-owner truck where the frame rust was limited (tough to find here in Michigan!).

Anyways, I went to pull my duck boat the other day and had no running lights. Brake lights and turn signals work. Tried the trailer on another truck, all good. Any suggestions?

I found the fuses underneath the driver rear seat, all seems to be in order there.

Thanks in advance!

 

Welcome to Tacoma World. Use a test light and confirm there is the 12v at the rear pug with tail lights on.

 

Did you check the light fluid may be low..!
Like said above check with test light also dirty connections will also cause them to not work.

 

Make sure you have trailer module, is my guess
