1979 Burro - Electric brakes

[Dave Mac]

I wired each wheel all the way to my wiring block at the front of the trailer. Now I need a 7 pin installed on my tow Jeep Wrangler and a brake controler.

Don't forget to use an auto-reset circuit breaker on the power connection to the brakes, per the controller instructions. I also use one on the battery-charge connection because the only way I would likely notice a blown fuse is when my trailer battery was dead...

Can you give me more info on this auto circuit breaker. What size do you use on the battery connection? Where did you purchase?
I'm looking into the Tekonsha P3 brake controler.

Tekonsha's web site for the P3 is still not as complete as for other models. If you look at the Prodigy page, you'll see the usual level of documentation, including a link to their generic Brake Control Wiring Instructions. As described there, the circuit breaker is in the line from the battery positive terminal to the control's power input lead (black wire).

Tekonsha specifies "20 amp for 1-2 axles, 30 amp for 3-4 axles"; with only one axle, 20 amps is more than high enough, but if the wire gauge is appropriate it is harmless to use the 30A rating.

I actually bought mine at an RV dealership, but they're common automotive electrical components, and only cost a few dollars.
