73' B3 340 Duster pro touring build

Go for it!!! You won't regret it. ISIS is great stuff, their support is incredible, they've had a few hiccups early on but they work hard to resolve any issues anybody has. They are seeing time in all different forms of motorsports and they stand behind their stuff. They've been nothing but great to me and I haven't even installed anything yet.

Can I make it work with factory gauges and switches?
