I use a regular SPDT relay for two amps and a fan. Relays will list the total amperage they can handle. Usually the max is 30.There are heavy duty ones that can handle up to 60 amps. My guess is you will not exceed that with your setup.

You will need to run a seperate fused lead for constant and use your current remote turn on from your radio.

Here is where to look... https://www.the12volt.com/relays/relays.asp
