It is on a fuse. Problem is, it is also the same fuse that is important like turn signals IIRC.
I am pretty lazy and figure out the easiest way to do something. I bought one of
these. It emulates a trailer with electric brakes plugged into your truck. That kills the alarm. Because folks with TT's don't want to hear it either.
Now the camper overhang or towing my boat on the flat 4 connection no longer set off the alarm. When I don't need it, I just unplug it and toss it in the glove box and my alarm again functions as normal, which is a very good thing when DW drives!!!!.
No need to crawl around under your truck looking for wires or connectors to disable.
BTW, the tape trick did not work on my 2011.
