Unhappy Installing gauge - where do I tap into the factory gauge light circuit ?

Does that make sense? I'm putting an aftermarket gauge in and want my factory light switch to activate this light also and possibly even be able to dim it with the rest of the interior lights.
Can anyone help me?

I haven't done it on the Mustang, but I added inside floor lighting in my old truck. What I did was probe the light switch bundle with a voltmeter for the interior lights then tapped that wire. You may be able to do the same from the dimmer wiring if nobody has an easier way...

A easy place to tap the dash light (dims & brightens with dash lights) is pop the clock off and use a test light to find the wire that comes on with the lights and dims & brightens with the dash light. I cannot remember the color.
Another option is to remove the dash and locate one of the dash lights and tap into it from there.
Hope this helps.

Maybe even the radio, easier to pull out and get to the wiring?

I just installed 2 gauges and I tapped into the wires at the headlight switch itself. I used a test light and touched the contacts on the back of the switch untill I found the one that had the dimmer.

This has worked great for me.

Good luck!

I have done the same thing as vibrantred94gt and it worked perfectly. That is the way I would suggest doing it. Take it easy.
