Trailer brake and Signal and lights not working

Hi guys,
I’m delighted bob took the time and energy to set up this forum.
I will try my best to explain my issue.
I have all but 2 wires not working in my 7 pin female receptor plug. Yellow and black. These wires are responsible for brakes and signal lights. I traced them to the first junction box under the hood. I tried swapping relays with the wife’s 4 runner and all fuses and now I am at a still.
Any information would help

 

Welcome aboard from The PSW.

 

Thanks buddy

Thanks Man ,
I have spent 5 hours so far on it tracing it back and fuckin with fuses under the hood however I have not messed with the flasher relay under the steering.
That’s tonight’s project
If this doesn’t work I might resort to an auto electrician.

 

Welcome

 

Thanks Adam,
I see you got over 45k messages and I’m thinking that you must be on the forum as a full time job. That’s a crazy amount of writing.

 

Welcome from the west side of the hump.

Yup, make sure that 30A “Towing” fuse is good, and in the correct location. Then check out the flasher relay.

 

Thanks landphil,who knows why the flasher is in such a shitty spot. I checked the fuse and it’s all good. I read rock auto are good for buying a cheaper flasher relay. I’m gonna see if Toyota has one in stock if not I will go for the rock auto.
