MKV webasto install

[golfi_vend]

Following my fuse-box thread I'm getting closer for installing.

I have a question about dosing pump wiring. What i've got:


I know missing frame and extraction unit. Anyways i have question about wiring.
I know GND goes to earth point 682, that is behind C-pillar cover, but where does the rubber plug, that is seen in the picture, go?
Surfing the web and ETKA, doesn't give me the answer.

Thanks.

Oh man, I want that so bad! My heater takes ages to warm up. My MK2 GTI takes about 60 seconds before heat comes out.

Are you sure you want it after you know what is needed to change ?

On my case I'm swappimg climatronic for mk6, new washer fluid tank, webasto itself, wiring, webasto dosing pump, new pipes and hoses for webasto and heater core, also the air quality sensor with wiring. If your car already has AC button and air recirc A button, then it's a little bit easier, cause no need to do climatronic wires and add air quality.
