Thanks for the replies.
I did not explain right. I do not have the time to get the controller installed nor the money. It's for just 1 weekend of use. I know my tug is heavy enough to tow with out trailer brakes (by law the weight ratio is fine). Will the trailer move with out the controller or are the trailer brakes locked on with no power going to the brakes? Thanks
No, the brakes are not activated if there is no controller.
One other detail in case you're not familiar with electric brakes: the trailer may/should have electric emergency brakes, which are actuated by a steel cable attached to the tow vehicle. The idea is for this cable to be pulled like a ripcord if the trailer gets loose, which activates a small on-board battery
to apply power to the brakes. I'd go ahead and clip that to the tow vehicle. Look for something like a small box with a big plastic key in it, with a stainless steel cable attached to it. Hook the other end to your truck. If it gets pulled by mistake, just re-insert it to turn the brakes back off.
