I assume you are talking about the relay rather than the aftermarket backup sensor. I would think that a standard horn relay would be a possible choice. These should be available at any automotive parts store. You could power the relay from the backup bulb socket as shown in the picture I posted above. Then you could pick up power for the other side of the relay from one of the two 12-volt accessory circuits. Unfortunately, this would mean running a power line from the console area to the rear of the car.
The accessory circuit should be a safe place to get power. I think it is protected with a 15 amp fuse. I would try powering the relay from the backup bulb circuit first before I bothered routing a wire from one of the accessory sockets in the console back to the relay. Don't drill any holes to route the power leads. Find an existing hole to route the wires.
Fortunately, the backup sensor I used had an adaptive power circuit. It did not make any difference which lead was connected to the plus or minus side of the bulb socket. I think you will need to determine which lead is positive if you use a standard horn relay.
