Good 12V light source after start up?

[simply86T]

I plan to buy some cheapo tinted lense gauges on eBay. These gauges need 12V source to be visible even during the day, so I am looking for good 12V power to keep the lights on after I start the car. I would like to know what source you guys recommand to tap. Thanks in advance!

best bet is to jam a voltmeter out, but I believe the cigarette lighter is a solid option.

Wait. Lense guage? So the lights are pretty small right? There is a 12V signal to your stereo. Shouldn't draw to much power

you can also tap into the harness going to the power seat, it can be peeled back to your left foot area but it's always on.... so you can use this with a switch for just about anything

I really really want an electric fuel gauge, but most them are $150+ from Autometer...... So I do what poor guys do and search on eBay, found this:

I know it's a ricey knock-off, but it comes with a sending unit. So I'm looking for a 12V that will stay on after I turn on my car and stay off after I shut her down, without the need of turning on light switch.

I guess if nothing works, I can always get a relay tap to the ignition switch and connected directly from battery, with a 15amp fuse of course......

Hm... I remember the backlight (if that's what you refer to) from cigarette lighter only comes on with I turn the light switch.......?

I haven't pulled apart a cigarette lighter in a z31 before, but usually the electricity ran to the lighter heating element is 12V. Take a peek, there's probably multiple hot wires running to it if there's a backlight too.

if you want cheap gauges i can get you some 2" carbon fiber gauges or white faced gauges for $45 shipped each.

they probably are not the best out there. but they are cheap.

Got any electric fuel pressure gauge including the sender? I know the sending unit along is $100 from Autometer......

The voltage at the cigarette lighter comes on at the 1st or 2nd ACC position.
I have the power for my boost controller tapped into it.

Y'all remember these gauges right?
