Towing a trailer without brake controller

My buddy has a boat trailer with brakes that needs to be moved. He pulls it fine with his 4 cyl tacoma no problem but he has a brake controller in it. Will I be able to drive it a short distance for him without having my own brake controller installed? His truck is not currently able to be used.
I'm not worried about the weight as I pull a 5x8 enclosed with no brakes that weighs more than this load. Just making sure the brakes are not engaged or something without the controller.

 

The brakes will not engage without power supplied by the brake controller. They will engage, however, if the break away cable is pulled from the switch.

 

Most boat trailers use surge brakes, not electric. No controller required. You can tell pretty easy by looking at the tongue.

For future info, electric brakes get power through the controller, that fires up magnets in the brakes. That pulls them to the hubs to create friction. Higher the V, the harder the brakes work.

Surge brakes have a box looking thing on tongue of the trailer. As you brake the vehicle the trailer continues forward, compresses a piston that creates hydraulic pressure that applies the brakes. So the harder you brake, the stronger the pressure from the hydraulics, the harder the braking. Until it overbrakes and bounces back, then the truck catches it, it pulls it forward again... surges.

 

Good to move without
