Roadmaster Even Brake - brake lite relay

I am presently installing an Even Brake in my 2008 Suzuki Grand Vitara tow vehicle. Roadmaster supplies an electrical relay switch which has to be wired into the toad brake light wiring system, depending on how it interfaces with the MH electrical system. Basically, if the application of the MH service brake sends current directly from the coach braking circuit to the toad's brake lights, in series with the MH brake lights, then the relay should be installed in the toad's brake light circuit. The reason for this is that in some (or most) vehicles, (like the Grand Vitara), when the Even Brake applies pressure to the toad brake pedal, the brake light circuit is still live when the ignition key is in the tow (accessory) position, so both the MH and the toad's electrical system are both trying to power the brake lights simultaneously. From what I have observed, this seems to initiate a fault code in the Even Brake electrics, and shuts down it's braking function, and sends an error message to the Driver's monitor panel in the coach. Installing the supplied relay between the toad's brake light switch and the brake lights isolates the toad's circuit from the brake lights while under tow, but allows the circuit to operate normally when the car is being driven. (The same thing can probably be accomplished by removing the toad's brake light fuse while towing, and replacing it before driving the car after unhitching, but I would like to use the relay if at all possible).
So, my question is has anyone here installed this relay on a late model Grand Vitara ? If so, I would like to ask you some questions related to connecting it into the GV electrical circuit. Thanks in advance.

I used the evenbrake on a 04 Avalance. I understood the relay was used to keep the car brake lights from coming on when the evenbrake pushed the brake pedal. This would cause the brake lights to override the the brake lights from coming on by way of the rv. The relay will not let the brake lights work when you push the brake pedal unless the vechile is running.
