Hi Eddys;
The Isolator kits comes with the PMD/FSD mounted on a the heat sink plate, 6 foot extension and mounting kit. I have had mine under 2 years and have 35,000 miles on it. Be sure to tell Bill your a Diesel Page Member and he MAY give you a discount. If you do a search for Heath you'll find out what the folks that have dealt with him feel about doing business. I think Heath and Kennedy are our two best 6.5TD vendors, they both stand by their products and are very helpfull. Both own or have owned 6.5TDs and their shops work on them regular. Hope this helps.

If you get the Isolator you can leave the PMD on your pump and use it as a spare so that if FSD/PMD on the Isolator craps out you can plug into the PMD on the pump till you get a replacement.
