RV Battery charge wire

[tkerrigan]

I installed my Prodigy yesterday and I need to put a relay under the hood to control the battery charging circuit. Has anybody done this and can give me a hint on a good location to cut into the factory wiring harness battery charge wire? Wire colors, terminal #'s? The factory charge wire also provides 12V to the brake controller, I plan on using a continuous duty relay controlled with a toggle switch.



Thanks in advance:

I use the Prodigy and just hooked it up according to the instructions. It powers off automatically a short time after you turn off the key.

With the factory setup, the battery wire in the receptacle is hot all the time. So if you have been on RV batteries for a couple of days, there is potentially quite a bit of sparking when you plug in. With the switched relay, I turn on the battery charging circuit after it is plugged in.

Hey, I forgot to mention it, thanks for the wiring diagram klenger. Is that from the disk version of the service manual?
