3 Way Switch Powered By Relay

I have a dump trailer with a three way switch powering auxiliary lighting. But now I would also like to tap into my reverse lights on my truck to power a relay to power the aux lights. So is there a way to have a relay to power a three way switch for lights?

I don't see why not.

You'd use the reverse power to power the relay, then use the Aux/12V rail to power your load.
