Hey I want to replace a simple on off toggle switch on my Bobcat heater with one that is variable/3 speed. It is a 12 volt system with just 2 wires. Many I've looked at have 6 wire setups. Can I use the 2 wire hot and ground on a six wire switch and how do I wire it? Below is a link to one of the switches I'm looking at. Thanks.
