fog lamps

I recently bought a front fog light wiring loom. My 2009 T5 has a rear fog light but no front fog lights, so the plan was to retrofit them. The wiring loom has six plugs on it (numbered in red on the photos). I know where four of them go (1,2,5 and 6). I do not know what plugs 3 and 4 are for...

Any advice on correct fitting, best options for front fogs....Not even sure if I need them?

Hi. I want to get a set of fog lights, switch, wiring loom and mounting brackets for my 2001 T4 Syncro. Are there any recommended good quality options?

In pic they r marked as 1B. Does anyone can help? http://vw.vag-zapchasti.ru/pm/e5e570bd.gif

Does anyone know where I can pick up a pair of Natural Grey (metallic) bumper inserts with hole for fog lamps please? And roughly how much? Thanks coBull
