I contacted our representative at Tekonsha about installing the Tekonsha Prodigy P3 Trailer Brake Controller part # 90150 on your vehicle with 24 volt system. There is actually a technical bulletin on how to install a brake controller on a 24 volt electrical system. You will need to go purchase a 24 volt relay from a local parts store in your area.

First, you will connect the White ground wire of the brake controller to the negative terminal of the first battery. Then you will connect the Black power wire between the positive battery terminal of the first battery and negative terminal of the vehicles second battery (see diagram). Then you will run the Blue wire of the brake controller to the trailer connector on the vehicle. The Red stoplight wire will connect to the load terminal of the 24 volt relay.

I am attaching the technical bulletin, which includes a diagram on wiring a brake controller to a 24 volt system.
