This is for ElectricAutometer Gauges on a 2005-2007 Mustang GT.

1> Run the 12v Switched(Red Wire) and Ground(Black Wire) from wherever your gauges are to the passenger side foot area. The White Wire(12v Illumination wire) is going to go to the headlight switch on the drivers’ side, but we will get to that later.

2> Connect the Ground Wire to a ground, I used the one found behind the glove box. It is easy to get to and only takes a second to hook up.

Ground behind glove box:
-Open glove Box
-Press in sides of glove box to lower out of the way(as seen in picture)


Once the glove box is lowered just back out the ground bolt(pictured below) a few turns, wrap the ground wire around it and tighten back down.


Now that you have the ground in place you can put your glove box back in place by pushing the sides back in and raising it into place.

3> Connect the 12v Switched wire to the fuse box in the passenger side foot well:
-I bought a mini add-a-circuit from Carquest


Connect your 12v Switched wire to the mini add-a-circuit:


Now plug the Mini Add-A-Circuit into fuse holder #13:


Here it is plugged in:


Now put fuse box cover back on and that part is done.



4>Connecting the 12v illum. wire(White) to headlight switch:
-Install the White Wire(12v illum. Wire) to the yellow/blue stripped wire on the headlight switch using a quick connector.
-Remover headlight switch from dash and let it hang with wires still connected.
-Use quick connector to connect the white wire from your gauges to the yellow/blue stripped wire on your headlight switch.



Push the headlight switch back in place and your done.

Now test your gauges.

Does this allow the gauges to dim then with the dash lights?

Mustanger

Yes, definitely, the white wire attaches right to your headlight switch, so they turn on when you turn your lights on and the dimmer switch is fully functional.

Muchas gracias, mang!!

Thanks guys I hope you like the write up, I couldn't find this info on the site so I did the write-up. And once I get my Saleen supercharger installed on May 2, I will add on to the How-To and show how I ran the wires for my electric gauges(boost and fuel pressure). I am just setting them up for now, so I can hook them up quick when I get the charger installed.

nice write up. I just used the power wire coming from my ignition. I'm running 6 AutoMeter Cobalt gauges off of it, and have the lights on the dimmer part of my headlight switch so i can turn them down when i feel like it.

I used your instructions and they are PERFECT
THANK YOU!

Notes: i measured the current draw of the autometer light
bulbs (using a power supply)....basically each bulbdraws
about 200ma @ 12v. i am installing a 1amp fuse
(in-line), for my illumination circuit, to help isolate my (4) gauges
from the cars wiring.
