Fogs - easy fit or nightmare

[sVWatt]

Anyone done retro fits on these fogs...
Welcome to VAGLINK online store
I assume the wiring loom kit will integrated with my existing lights switch, or do i need to buy a light switch with front fog option in it ?

I found the same link and emailed them that same question.

the loom they supply is a generic foglight wiring kit. It comes with its own switch which mounts under the dashboard.

The new Polo uses multiplex wiring which means there is no direct link from the headlight switch to the foglights. Instead, the switch sends a digital message to the car's computer, which sends a message to the lighting module, which turns on the light. Tricky! (the explanation is not exactly accurate, but you get the idea.)

This means you can't just connect to the light switch, even if you were happy to have the rear fog light switch also turn on your front fog lights, which is what I did on my partner's SB Barina.

I have spoken to several VW dealers about getting fog lights fitted to a Polo. The only option they offer is the sports pack, and I definitely don't want that. The service departments all told me to forget about fitting them aftermarket because of the multiplexed wiring. I went online and found the same link as you posted. I can see one way to do it (other than just fitting the underdash switch) is running a wire from the rear fog light (right at the light, to avoid accidentally connecting to the digital parts of the wiring loom) to a relay under the bonnet, to switch the front foglights on when the rear foglight is on. One dealer (car salesman, not service department) said they could do that.
Note that if you accidentally connect the lights to the wrong part of the wiring loom, not only will it not work, but you also risk destroying the car's main computer which will cost thousands to replace. It's been done before... (not by me.)

Have been looking through the wiring section of the manuals and mate, Nightmare is the simple answer unless you just connect using a generic switch that is dash mounted.
