I've had the entire dual bat kit on order from IPOR for 2 1/2 months now. It uses the surepower separator. Long story and my patience is just about out.
Cancel it, get the Hellroaring isolator and follow Cruiserdrew's installation. It is a 2 banana job but I have officially promoted you from 1/2 banana to 1 full banana. Doing the dual battery with the Hellroaring kit will make you a candidate for the 1.5 banana designation with 20 points extra credit for advanced electrical work. (That is, *if* you don't burn up the truck, the garage, and half the house.

stop by and I'll help you with a Hellroaring install. I have the crimpers and the stuff you need.
