I found on one of the many forums I've been reading that you can install a relay to by pass a switch to have lights activate. Toyhaulers have loading lights over the rear ramp. Using the relay idea, I installed one inside the wall, tapped into the hot wire before the switch and the load wire going from the switch to the light, used the ground wire also and only had to fish the wire ALREADY in the trailers wiring harness coming from the 7 pin connector to the reverse lights on the truck, through the wall from under the trailer to activate the relay. In my trailer, it is the yellow wire. The 7 pin to trailer tongue has a junction box and I had to splice it together inside there, and then traced the wires all the way to the tail lights and the wire was there, but NOT used. Pulled it out of the 7 wire bundle and fished it up through the weather membrane into the wall where the loading light switch was already. Works great!
