[W126 Coupe] Headlight installation help

[stefansj at canisius.edu]

Hey everyone, I installed my euro headlights today and it was surprisingly very 
easy. My car is a euro model so everything was there I just had to take the 
american lights out. When I did this I found that the 6 prong plug was there 
along with the purple vacuum tubes. The headlights turned on no problem but 
the lower fog lights did not work. I plugged them into the headlights correctly 
and check the connection with no results. If anyone has any ideas I'd really 
appreciate it! thanks, Jas
