Polo GTI - Boost Gauge Wiring

[hail10]

Hi all, this is my first post in this forum Been reading old threads, there is some very informative info and knowledgeable members.

Today I decided to install a boost gauge in my GTI, it all went smoothly after a few searches on the forum, however I've had some trouble with the wiring for the lighting. I know how to remove the headlight switch but I'm unsure which wires I should tap into so the gauge lighting will work with the rest of the instrument cluster. Any help or advice would be appreciated.


Thanks,

i just hooked mine up too.
use the stereo cable for pos+ power, ground from underneath of the top centre tray on the dash.
and illum i use the cable from ciga light. remove the two screw and lift the centre plastic panel up to gain access to the cables.

Can highly recommend one of our own ... Jimmymac on this forum (in Bris). (He's looking after my 'baby' while I'm in NZ.)

Of course ... that doesn't really help our Sth African friend.

Thanks alot for all the help guys, I do appreciate it. Finally finished the install today and its working perfectly. I'm very pleased with it. Was easier than I expected, thanks to the good guidance. I'm glad I did it myself, it helps to learn a few things about the car as well as gives a sense of satisfaction with a job well done.

i ran mine through the rubber stopper on the side, near the door hinge.
steps:
1. remove front left wheel
2. un-screw plastic wheel acrh cover
3. un-screw & remove another plactic cover near door hinge
4. run the cable thru the front of left fender near the headlight (in the engine bay), thru the wheel arch.

hope this will help
