    Do you disconnect wiring before launching

    Another thread about a Ford truck not recognizing the trailer got me curious enough to look up the manual for that truck. While I didn’t see anything about that issue that hadn’t been said in the responses I did find a note that the trailer’s wiring should be disconnected from the truck before backing into the water.

    I looked at the manual for my Avalanche and there is no warning like that. Is this something unique to the F150? Is Ford just doing a CYA?

    Trailer lights are all sealed now so you don't need to unplug.

    I don’t remember ever seeing anybody do it. It must be something that the lawyers made them put in the manual.

    Ever notice how many warning labels are on a ladder?

    My father always did however I have never disconnected. So far I have never had a problem. My thoughts are heavy rain habe never caused a problem so why would putting the trailer in the water do it.

    Years ago lights on trailers were not sealed like they are today, and usually when backing in and as the water enters the lights and the bulbs being hot many would either burst or the filament in the bulb would break. The remedy for saving the light was to unplug them while you got the boat ready for launch which allowed he bulbs o cool.

    For those that didn't read the other thread I should mention that this was in the manual for a 2013 truck. It was also warning to not let the water get above the bumper on the truck and to service the differential if it got wet.

    My dad always does. If your lights aren’t sealed then you should. But most boat lights today have a rubber gasket and are waterproof so there’s no need.

    I don't disconnect the trailer wiring so that I can back up without putting a manual lockout on the side of the actuator.

    Indeed. Hitting the brakes in water with a red hot 1157 brake light bulb would blow them up.

    Truck differentials frequently have a vent tube that sticks up well above the axle, it's best not to get water in there.

    You must have a very old trailer and or light fixtures. Most today are LED and sealed. No need to unplug anymore. :-)

    I remember when I was a kid...we always carried a bunch of 1157s cause I would forget and as soon as they trailer hit the water they would go pop, pop...no more lights. The little things have changed a lot.

    Do you guys really think that Ford is trying to protect an old style bulb that is rarely used anymore instead of laying the groundwork for denying a warranty claim on the truck’s electronics?

    I have a 2013 F 150, and of course it tells you not to let water go above the bumper of the truck, lol Believe it or not, there are people that don't have enough common sense to know that. As far as unplugging the trailer wiring, not since the old days.

    Warning for rookies



    If the water is entering the cab at the bottom of the doors——— you’re in too far, pull ahead.
