Guage lighting update for the CSOB, Electro Luminescent illumination for your guages! Options

[Rotary'14]

Porsche Gauge illumination upgrade/modification.
For this write up I’ve used a 914 Tachometer, but the method is similar for other Porsche VDO gauges.



Pointers appear dim, but this is a short coming of my camera.
In real life pointers are easy to see.



Tools you will need:
Small flat screwdriver
Scissors
Soldering Iron
Wire stripper
Crimp tool

Parts you will need:
2 wire connectors
wire
Small diameter heat shrink tubing
Clear packaging plastic(saved from trash)
Scotch tape
solder
5 feet of Electro Luminesent wire
12v inverter for above wire



Gauge Dis-assembly:

First thing is to open up the gauge. This is done by prying at the bezel with a small screwdriver. Work around ¾ of the circumference of the gauge. It should be possible to remove the front trim bezel holding the lens in place. Beneath the lens is one or two additional bezel trim pieces (depending upon year of gauge).


Examine the rear of the gauge and you should notice 3 or 4 small flat head screws. These hold the gauge mechanism in place. CAREFULLY remove the mechanism by loosening the screws, and set the mechanism aside.

We only need one inverter for any number of gauges. This inverter gets it’s power from the original lighting circuit off the dimmer. Yes the dimmer works too!! It’s a simple 2 wire installation. This inverter’s output needs to be split as many times as there are gauges. I chose to use a quick connect to make service/installation easier.
