Help...Wiring Seat Switch-W126
I am replacing the driver's seat switch on my 1981 300SD. It all makes sense except for one wire. What wire goes to the contact labeled "R" (see attached photos). It would appear that there is no positive feed to this side of the switch, so does this mean to run a jumper from the large red wire going to the lower harness? This would seem to make sense, but there were no instructions with the kit. Thanks.

Hi Guys,
Never mind the question. After a little experimenting I figured out that you do indeed have to run a jumper from the red wire to the post labeled "R". This gets power to the switch that controls the back of the seat...just in case anybody else runs into this problem. CW

Changing a seat switch should be plug and play, did you add the later ones with memory?

Up to late 1982 the switch was a soldered connection, wires direct into the switch. So later car switches/replacement switches need to be "updated" to the plug to install properly. Mine is this way so I will have to do this too when I replace both of mine (they are both broken). All W126 produced after late '82 have a plug-in connector....eliminating this issue and making it plug and play.

Ahh MB did one of their updates. Kind of like the dome light on the W210 after 2000.
