Hi Bob,

240 Central Locking didn't change much over the 19 years. Same colors being used: blue and yellow for the motors and red and green for the switches. The two locking relays have always been on the rail behind the center vents.

Changes I'm aware of are related to the '86 revision of the trunk, so it is included in central locking, and the surprise I got when finding a 242 has a lock motor in the driver's door (and an unlock switch on the armrest panel).

The chief cause for trouble remains the insulation falling off of the wiring on the lock button and key switches, followed by broken wires in the door jamb. I've never heard anyone say the relays were a problem, so advice to check them is not from experience, and because of where they are, and how difficult they are to reach, enough work to get you angry at anyone who suggests it.

Here's a map of the 92-93, which covers the '89.

It was the accepted practice in Babylon 4,000 years ago that for a month after the wedding, the bride's father would supply his son-in-law with all the mead he could drink. Mead is a honey beer and because their calendar was lunar based, this period was called the honey month or what we know today as the "honeymoon."
