Re: 2015 3/4 w/trailer package

My trailer is a dual axle but only one has brakes and I read that the computer has to read enough resistance to acknowledge it has a trailer with electric brakes. I will hook it up again without the truck running and see what the DIC indicates. Supposedly one 12 volt bulb to ground on the trailer brake pin is enough to look like a trailer.

May try it if needed.

tks
