Will Tekonsha Prodigy P3 Brake Controller Work on Triple Axle Trailers

Question:

I viewed the diagram you showed for wiring a brake controller and my concern was the amp draw for triple axle electric brakes plus brake lights might burn up the brake light switch circuit wiring. The circuit that goes to the brake peddle switch is low amperage verses the load draw of triple axle electric brake plus brake light. In the new tekonsha P3 controller does the RED brake switch lead trigger a relay to energize the BLUE power lead so you dont fry the wiring to the brake switch. Thank you

You can use the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 on a triple axle trailer with no worries about the wiring getting fried; the P3 is actually able to work with up to four axles and eight brake assemblies.

If you are hardwiring the controller in you will need to make sure you use 30-amp circuit breaker # 38630 with your six brake assemblies. The low amperage on the red brake light switch is because it only needs enough amps to light the signals; it will not fry the wiring to the brake controller in any way.
