Hey Reese, if you indeed have 24v throughout the vehicle, you'll need to get a 24v to 12v step down reducer / converter to do this. Sorry to say that we don't carry any, but they are relatively cheap on other sites. They are simple to install. Then you can install universal 4 way like # C58044.

One thing I'd check is that you actually have 24v going to the tail light circuits (use a voltmeter). I'd imagine that you have 12v already at the tail lights, which means you could just install the universal Curt 4-Way Flat Trailer Connector w/ 60" Harness and Wire Taps # C58044 without anything else.

Let me know what you find out! What are you towing behind the bus?
