  • Good Isolator for the money

    I have had this product for over a month and It has lived up to my expectations. The isolator has done everything I needed it to do. I installed it on my 99 GMC Suburban 350 c.i. for recreational use and it works like it said it would. Set up is a little hard. Deffinatly do your research before installing. The instructions aren't much help and the pictures dissplayed are not the same as they are on the issolator (terminal placement). Doesn't come with any connectors and for my truck I had to get a new plug for the alternator so I could hook the Isolator up properly. The auto parts store had a universal plug that had all the wires. This product is good for the money.
