I have an Ez haul 8 bale trailer that I pull but in in order to haul all 8 bales I need someone in the truck activating the bakes so the truck doesn't move as I push on the last couple of bales. I was wondering if I could tie into trailer brakes with an upfitter switch so I can activate the trailer brakes with it and load bales myself. Has anybody tried this??

 

I had the same thing but I don't have any help on the farm, I use a rubber band on the lever to hold it maxed out.
Probably not the answer you were looking for, but it works for me.

Don't see why not. Should be the blue wire on the brake controll wiring harness. But an easier way might be to just pull the breakaway cable out. It pops right back in.
