Tail Light Short

Hey Everyone.
Im having issue with my 2001 Tacoma V6.
The problem is do to a short that keeps instantly popping the 10 amp for my tail light and speedometer light. I've tried unplugging and changing all rear bulbs. Unplugging radio, heater, and changing tail relay to no avail. Do anyone have ideas on what to check next? Or maybe have had a similar issue that they have fixed?


Thanks for any help!!

 

Do you have trailer wiring? Any added on aftermarket items? Like radio or lights?

 

Second on the trailer light converter box

Rubbed wires some place

Drill any holes quite a few manage to drill through wiring harnesses

 

Check the trailer light connector closely. Look for corrosion.

 

Thanks all for information! I'll definitely check the trailer light as a next opinion and I'll let y'all know.

 

Yes a aftermarket radio that I 100 unpluged.

 

Heres everything on that circuit. Check all the wires around the radio connections also.

 

Okay thanks!
