I can't say enough about how much I love my Isspro Performax gauges. I finally got around to installing my HPOP gauge yesterday and it literally took me under 5 min. The great thing about Performax is that when you add additional gauges all you have to do is run the sensor wire to the ESP and then go inside the cab connect the plug to your gauge wires and pop it in the dash. This is the ultimate PMS tool, and it is great because everyone knows that sooner or later you will move on beyond the "standard 3" everyone starts with. It was awesome to be able to run my 3 wires to the cab one time just the way I wanted, secure them and then never touch them again. I always hated the idea of having to feed more wires through the firewall every-time I upgraded. Here are some pics to help show how everything is run.
