I hope someone can tell me what I've done when I rewired the harness to match (looking into the plug end), what was indicated on the F350's harness diagram. When I say match, i mean if you were looking straight at the end of the plug, and into the plug on the truck...
We were on our way to camping world to have a new water heater installed, and a few other things done to the trailer...
I no longer have an airstream, but now have a silver streak (1975).
Everything was fine until my husband turned on the engine and started to move the trailer, where he said it wasnt moving well? then the brake controller started to smoke... we quickly pulled over and disconnected the plug from the rear, and the brake controller, which i assume is toast.
we finally got the trailer moving again (using the temporary lights that have magnets on them), and have left the trailer at the RV place for repair.
While trying to disconnect the RV from the truck, the switch to raise the trailer and put the wheel under it didnt work? I don't even know if any lights work at this point... i feel terrible - have I totally blown it?
Not having the diagram here I know I put the black wire into the center of the 7 pin connecter, but cant remember the others. All the lights worked when we tested them, which is why I cannot figure out what went wrong... signal lights back up lights (with engine on), running lamps... all working!
