Not sure if this is where I should post this, but where is a good place to ground a pyro?

ground it? as in electrically? it should ground itself in the exhaust manifold. and the wiring will just hook up to the gauge

Ground the pyro? Screwing it into the exhaust manifold should be enough!

weird i had an autometer elec and i grounded the gauge portion to the dash supports and it worked fine. But running it to the grnd on the battery is never a bad thing

Grounding

My Isspro had to be grounded because it goes through an electrical box to insure smooth operation. I simply grounded mine on a screw in the knee quard of the dash.

I thought he meant the actual pyro probe having a separate ground wire. My ISSPRO gauge box is grounded inside the cab and works just fine. Just make sure it is a good ground - no paint, etc.
