Installed triple overhead on my '05. I used autometer phantom fuel pressure, EGT, and boost. Everything was cake except for that the wire for the EGT gauge that comes off the thermocouple was just barely long enough to make it. I had to carefully plan my wiring to make it fit. I was told on here that that wire is a "K" type wire that should not be cut. Also, the directions that come w/the gauge say that if it is lengthened or shortened it may affect the callibration of the gauge. Pod needed to be trimmed to fit nice, but no biggie. I got everything from Geno's. They give you nice instructions and the "boost bolt" for the boost gauge. I used the billet fuel filter cap and that was also a breeze. Mounting tape/velcro works nice. Doesn't move or fall off. I had A-pillar mount on my last truck and think that it may be a little easier to glance at that set up while driving, but I still like the rear view. It's something different. Good Luck!
