Where do these go?? 1 green and 1 red cap + 1 small diameter grommet? I tried calling AutoMeter, but call connects, says “goodbye” then hangs up!

you can probably run it through the factory grommet that all the stock wiring goes through as there was always plenty of room for me to run a 4 awg amp power wire through them when I was installing. Otherwise when it comes time to drill you just need to find a spot that you can see on both sides. Say it is 3" to the right of the brake cable on one side, look 3" to the left on the other side to see if it is clear. It is also helpful to make a small hole first and then you can shine a light through it to ensure it is where you want it. Small holes are much easier to fill/fix if it is off a bit than big holes. I normally do a small hole first and then use a stepper bit for the larger.
Where is said “factory harness that all the wires run thorough that a 4 amp wire will fit through ”?? Where do I look to best find this? The engine side of firewall or interior side up under driver side dash?

I’m embarrassed that I’m such an idiot about this, but I’m determined enough to swallow my pride, confess I don’t know, ask for help and learn how to do this. The gauge itself and the probe are easy enough, but it’s the wiring and drilling (or locating the wire harness to run the cable through) that are my stopping points right now. :-(

realistically incandescent bulbs do not matter +/-, but diodes do. Yes I would do white for power, black for ground.

lay down on the floor on the drivers side and look up behind the clutch area and you will see where all the stock wires go through the firewall. Around the outside of the harness is a really thick gasket that you can poke a hole in with a screwdriver and then run your wires through. You might need to use a coat hanger as a fish-tape to get the wires through.

Thx, ttocs that helps a bunch. And while I’m upside down under there, which wires am I looking for to splice into? Do they have specific colors?

There should be an ignition wire in the gauge area that could supply power for it. I do not know the color off the top of my head, let me see if I can find my wiring bible and find it in there.

It’s in and functioning properly:)
It measured between 190-210* on the way home, which was a “spirited” uphill run of 3-4 miles.

Is the 190-210* range ok or too high? Wondering if I need a different thermostat. I have the Mishimoto now
