Post by: zenicman9 on February 17, 2012, 01:00:35 pm

Hi All

I have some fog lights and I am looking to wire them (not to the main loom) does anyone know what wires I would need?

I am going to put a button in the centre console for them any suggestions :

I did once on my passat B5.5, bought wiring loom from Halfrauds, calls fog light wiring kit, costs around £15.

Yes I believe they do, you get relay, wiring and instruction with,it was straight forward job on passat. I believe with MKV you will need Vagcom to activate fogs after install.

You can buy any 'spot light wiring kit' from eBay/Halfords for £10-15. It will come with wiring and probably a relay.
You just take a direct, fused feed from the battery or another thick 12v constant supply somewhere in the engine bay.

I did this years ago on a 206, can't see how you need VCDS as this should be totally independant to any control module (depending on how you wire it though).

If you Google for a guide, it will apply from any car as this is a seperate circuit you're putting in. It only gets complex when you start taking a switched live, tapping into sidelights etc.

In my old car I just had them wired direct to the battery, and used them whenever I needed but had to remember switch them off with the ignition off (battery feed = lights stay on until switched off manually). Make sure you get a switch with a neon/light indicator.

I'd also suggest you get the fog connector plugs and a few inches of wiring to solder onto as it makes a solid, watertight connection.

When I did it I ran the wiring straight into the switch which was a 205 GTI fog button, there already was a dash cutout for this anyway. This button had a relay built-in.

In my opinion, I would look into doing it properly as a retrofit. I know it'll be much more expensive but in my old car I hated the DIY way of doing it and ended up fitting it via the car wiring (process similar to a Golf).
