Hi, I have a set of stewart warner maximum performance boost, pyro, and trans temp gauges installed on the pillar. Had a shop do this several yrs ago. Trans temp really never worked. Pyro failed a little over a yr ago, it started making a humming noise then just froze at 700*. Hadnt been too worried about it, dont drag race or pull insanely heavy or lug the engine in o/d up a hill, gauges lights up and everything, but now planning on doing some things where I will want to monitor egt. The gauges are grounded near the hood release, along with my fuel pressure gauge, and positively spliced into a solid blue wire in a harness right behind the hood release. Not sure if the gauges are just bad or what. wanted to see if I could fix this myself before I take it to a shop. Thanks, Rick
