Relay for remote

I have a wireless remote to turn on the main power for my neon lighting. I decided that I want to use the remote as the trigger for a relay and run an 8ga wire as the main power wire supplying power to the neons.

how would i wire this to a relay? would i need a diode on the remote wire to protect that?

thanks

would there be only the two wire to hook up the remote 12v pos. and the 8ga. wire??? What leads on the relay would i hook them up too?

thanks

85 switched ground out from your alarm

86 +12v FUSED

87 +12 FUSED

30 out to the + input of your neons.
