Tail Light Short

Hello Tacoma World
I have a 2011 TRD SPORT 4x4 and The tail light fuse keeps popping when the headlights are turned on. The brake lights work in the blinkers work headlights work. It’s just the tail light fuse that blows. I have removed both taillights from the circuit and the fuse still blows. Any of you guys that have access to wiring diagrams for this truck? I need to know if there are any other lights or accessories that this fuse powers so that I can look for shorts somewhere other than in the harness from the tail lights to the fuse box. Any help would be appreciated thanks.

 

Got a Trailer connector...

 

Factory as far as I know

 

You tried unplugging it...

 

It powers all of the interior illumination (backlighting) as well including the radio, you haven't swapped radios recently have you?

Also do you have the Towing Package? (easiest telltale is the presence of the oil cooler under the oil filter).
If you don't have the Towing Package then the Towing Converter would be suspect.

 

I Did swap the radio about 2 months ago, I don’t have the towing package. What’s is a Towing Converter?

 

It's a box that is typically plugged into the tail light harnesses that "converts" the truck lighting signals to the trailer plug, if you follow the wiring from your trailer plug you should find it.
They tend to be problematic with causing lighting issues/shorts.
