| CENTRAL LOCKING PUMP & CLOSING ASSIST PUMP INSTALL
I'm about to take delivery of each of these 2 pumps for my 92 600SEL - one in the trunk, one under the rear seat. Can anyone help with installation tips? Is it as straightforward as removing the old and plugging in the new, or is there other preparation/setting required? I'd be grateful for any help if you have undertaken this. |
