Yes again another trailer brake light problem
#11
So today I poked around under the dash, removed the brake light switch from the brake peddle, opened it up and cleaned the contacts. After putting it all back together both trailer brake lights work again !

Go back to basics
Start from scratch and conferm that the truck was wired properly and then that the trailer is wired rite too.
