Trailer tail lights

I have a 2019 Trd off-road with towing package I plug my trailer in and popped the fuse I fixed the trailer short then replaced the fuse. I have no power going to the trailer tail light but do have brake and turn signals. I have metered every fuse under the dash and hood everything is good Does anyone know if there’s any other fuses or anything else I need to look at

 

Check the bulbs.

A dual element bulb is used for Running lights (one element) and the Brake/Turn lights (second element). The bulb is probably an 1157 type automotive bulb.

 

I have no power on the pin for the tail lights on my truck on the 4 pin or 7. Everything else works as normal. I am not getting power to my bumper from the dash or fuse box. The fuses are good and I have voltage going thru all the fuses but lose it some between them and the bumper

 

1st make absolutely sure the 30A Towing Tail fuse is good.

Do the tail lights on the truck work?
I ask because the 30A Trailer Tow relay grounds with Tail Light relay for the truck.
Take note here, there are 2 Tail Light relays. Tail and Towing Tail.
If the truck tail lights work, you will need to pull the towing tail relay and check for power there.
If the truck tail lights don’t work, we’ll it’s going to get a bit more complicated.

BTW, you posted this in the 2nd Gen section.
But we can surely help you figure this out

 

Maybe because the towing tail fuse is in the engine bay fuse box...

 

Yes my truck is all working and I checked power on the relays and fuses.

 

Check all the places @caribe makaira said above.

If the fuse is good, pull the relay.
See if you have power to the relay. 2 should show power. (Pins 2 & 5 in the above diagram)
If you have 2 showing power, you need to test the relay.
If the relay is good, than you have a ground issue, a Body ECU problem (not likely), or a wiring issue from the relay to the Trailer Tail lights.

You could ohm the wiring out (safest way) , or jump the relay (pins 3 & 5) to test the tail light wiring.
DON’T jump the wrong terminals. As you risk damaging the Body ECU.

@caribe makaira might have a Relay Pinout diagram.

I know you said the fuse is good, but I’m still sticking with that for the time being.
If that’s definitely not it, then the relay or wiring.

 

Yes I checked the relay and the pins. Power is good I have the towing package so not sure if that makes a difference on the wiring harness but I’m sure it somewhere in the wiring just not finding it

 

Remove the relay, set it aside.
With a multimeter, check slots for pins 1 & 2 with the light stalk turned to parking lights.
