73' B3 340 Duster pro touring build

I'm always amazed .... tonight is no different. I'm looking into the Isis wiring system for the Demon. I have to purchase a new ralley dash harness and a new engine harness so the cost of the Isis system wouldnt be much more.......

I've heard good and bad on the ISIS system.....Google some reviews before you $$$$$$. I'm probally going with Keep it Clean wiring harness....since I get a 30% discount. Thanks for the support.
