Wiring Gauges in Dash Hole - S10
 

I've been thinking of a few things I could use in the truck. With a small amplifier and sub, I want to be able to cut off the power to it quickly for phone calls, etc. Maybe some green LED glow in the interior, etc.

What I've ended up with is a design for a panel that has a Voltmeter and Thermometer, with a switch to turn those displays off, an amp switch, a switch for LEDs in the foot wells, and an indicator light for the (future) eFan.

However, I'm not quite a rocket surgeon when it comes to electrical wiring. I come to you, the Community, for guidance and assistance...

Here is the hole under the CD player, it measures 174mm wide by 24mm high, but I can remove the bottom plastic to make it a full 30mm high.

I will be using an 8-pin Molex connector to wire it into the truck, keep it clean and easily removable.

==LEDs, with resistors: DIY 10mm 1W 8lm Green Light LED Bulb (DC 12V / 10PCS)
==Digital Voltmeter: 2-wire Car 0.56" DC 3-30V Green LED Small Digital Voltmeter Panel Gauge - Amazon.com
==Digital Thermometer: Green-LED-Thermometer-Digital-Fahrenheit-0-167-F

My questions are... Does my wiring look correct? I should be able to do a common ground for all this, right? Should I use one of those add-a-fuse things to bring power from the fuse box, or is there a better method? Thanks!

The wires look good. I would make sure all the switches are on a fuse.

Thanks Dave. Would I add a fused circuit from the fuse box, or use one of them add-a-fuses from the fuse box? Hopefully you don't mean each switch individually having a fuse...?

I would use an add-a-fuse and have that go to a fuse and the switches from that.


add-a-fuse > 25A+ fuse > Wire to switch box > switches.
