My dad is asking me to find out where II's have a "12 volt switch power source". Does anyone know? We need it to hook up the electric fans and electric fuel pump.

Thanks for any information.

You need to switch a relay on and off to power fans. DO NOT WIRE THEM THROUGH THE KEY SWITCH DIRECTLY. All the amps that the fans draw will burn out the key switch. I found this out by running fog lights without a relay.
