    Fitting relays

    Probably a daft question but I need to fit a new airmatic relay which has arrived. I assume it is just a case of whip the old one out and stick the new one in? I wouldn't ask for my older cars but this e55 is properly complicated electronically so it seemed sensible to put the question.

    '83 W123 diesel: glow plug and flasher relays

    Anyone got these parts surplus, or breaking a car? They're for my 240td but I think a 5 cylinder 300d glow relay will also fit. I'll add the part numbers later. Cheers.

    Installing & Removing relays in rear SAM with battery connected?

    I have a long awaited relay which I need to install in the rear SAM of our W164: are there any must dos and don'ts when it come to fitting? I assume it's the same as a regular fuse, so engine and ignition off, but with battery connected is the order of the day - is that right?
