Thanks for the thought DSSA. I did look in that area without a diagram. It is a spaghetti bowl. That is the place I will go back to if I don't get any other responses. I was hoping to find a fused power source. I tried to find diagrams but they appear to be hard to come by. If I can find a switched power source on the right side that is fused from the front fuse box, that will probably work just as well.

Just so you understand. I recently installed a hitch rated for 600/6000 lbs. I had a Curt light controller installed with an adaptor for a 7 pin to provide the 12 volts to the Prodigy RF break controller.

All is well and good except I would like to install the Tow Ready battery Isolation solenoid to turn off the 12v to the trailer when stopped. I just can't find a suitable switched power source to run the solenoid.

Thanks.
