I just bought a fuel pressure gauge, and I just wanna make sure I know how to install it. I thought I'd just buy the adapter (linked below) from ZZP, but is that really worth 10 bucks, or could I get it somewhere local for cheaper? I need a -4 AN femal to 1/8" NPT female adapter, correct? I got the gauge linked below by the way.

I could also use some input on how to wire it up for the backlight. I don't care too much if it can be dimmed with the dimmer switch, but it'd be nice if it's easy to do. Mainly, as long as it comes on and off with the headlights I'll be satisfied. I've heard about a "power drop" under the glove box on Grand Prixs; does my Monte have this too and should I use it? I can handle doing the wiring, I just need to know what wires to use.

Thanks.

 

Anyone know the best way to wire up the backlight for the gauge?

 

Ok, I've got all the parts (I think) that I'll need to install my boost and fuel pressure gauges. Just looking for any tips or hints. I could still use some info on wiring up the backlights.

Also, to those that have installed gauges on a 6th gen Monte, where did you run the wires/vacuum tubing through the firewall? I think I see a suitable grommet but it looks like it'll be a pain to access from either side. Any suggestions and a pic or two would be nice.
