any 12v relay will do you can pick one up from an automotive shop if you don't want to wait on shipping...this is assuming your just needing a relay to pull power to another source when the remote comes on....just ground one side of the coil 85 or 86, remote to the other, 12v at 30 and the wire(s) to what you need 12v to at 87a
