Downtown,

The isolator is the part of the system that separates the batteries so they can operate independently. The aftermarket one that was on the truck we have looked like a small stereo amplifier. To be honest, I'm not sure what the factory isolator is suppose to look like 'cause our truck didn't have it. According to Wes at Classic Heatbeat, he's sending us a harness with the isolator included. Thanks for the offer on the tray and stuff. We may end-up needing extra parts if we decide to create a kit so I'll keep you posted. As always, this board and it's members have proven to be an awesome resource, thanks everyone!!!
