Awsome. My 2003 has the same fuses behind the seat. 3 yrs ago while fishing a lake several hundred miles from home my trailer lights died. I checked everything I knew how and then took it to a local mechanic. He said the problem was in the truck and probably a converter box. I drove another 120some miles to the nearest dealer. They checked it and said it was tghe converter box. They also said they didn't have one and none were available in the USA but they could order one from Japan/ This being a family site I won't share what I told them. The suddenly found an after market one at the local parts store. I now wonder if that was also the 50 cent fuse that cost me $180.
Tanks for the info. Got them going with just a fuse. My TLR lights went out again a few days ago.
