HELP! Euro(UK) '88 300SL, location of front vacuum connector?

[coleyjf]

Hi all

I'm still trying to locate an errant central locking vacuum problem on my 1988 UK/Euro 300SL. I've pretty well narrowed it down to the FRONT vacuum connector BUT I CAN'T FIND IT!!!!

The attached vacuum diagram I've obtained some time ago shows the layout and it seems to describe my model, however I've checked all the door locks and the rear connector (in the boot) but other than taking ALL the trim/covers/panels off inside the car I'm wondering of anyone can point me in the right direction for the item circled on the drawing please

Bearing in mind it's a right hand drive (the proper side ) there may some differences but as the vacuum pump and the rear connector are on the RHS of the car as shown on the diagram I'm assuming it's a standard on all models RHD (UK/NZ/Japan etc) and LHD (Europe and USA)


There is only one pipe into each door so it's not in a door!


Help much appreciated

Cheers

Jim
