Gauges set up!

[illtal]

I ordered a prosport evo premium oost gauge and fuel pressure gauge that I want to install sometime soon. I've read the threads related to wiring for gauges, watched a couple videos, etc. I wanted to ask where you guys were tapping for constant 12v power (or are you running a wire to the battery) and accessory power, and if anyone was actually wiring for the dimmer switch. I see reference to wiring the dimmer switch, but please bear with me as I struggle with wiring. If anyone has an answer or can point me to a thread or something, I would appreciate it.

Edit: they sent me 2 fuel gauges. I guess I have a few days to figure out the wiring while I wait on the boost gauge to ship. Frustrating.

I have the same two guages: right now just prosport digital boost

Do you remember how you wired it or where you looked for the info? I had a nightmare once in the past where I tried to tap a fuse and bent some contacts under the fuse box that resulted in some of the wildest issues imaginable lol.

I didn't hook it up but the auto dim function and everything works

Okay, I'm back. I am trying to figure out where to tap/splice for 12v accessory power. I bought an add a fuse but it isn't the right size (mini) so if I can just splice a wire that would be great.

Edit: gauge is prosport evo premium with wires for 12v constant, accessory 12v, and dimmer. I assume the accessory is what I need for basic power when the car turns on/accessory is on and the constant is just for memory settings.


Edit: so I wrapped a wire around fuse 2 in the passenger fuse box for accessory, wrapped one around fuse 3 for constant 12v, and ran a ground next to the fuse box. Gauge isn't getting power though, but the fuse 2(power windows) is good because the windows work. Any ideas?

Edit again: tried changing accessory to fuse 53, cigar lighter, in the engine bay. Still no power. Is it my ground? I am just trying to find the right places to run wire, I will clean it up once I know it works.


Edit: I figured it out. The damn harness for the gauge has the accessory wire and the ground wire colors switched.




One more edit: what size is the fuel line? I need to get a t fitting for my fuel pressure gauge.
