I think you want these. the first two are labeled. DSCF0016 is the OVP relay (red) and the courtesy light (timer relay silver).DSCF0022 is the Cruise control amplifier left and windshield wiper relay right. DSCF0026 is a picture of the windshield wiper motor, which is easily accessible from the bottom with the foot cover removed and heater duct removed.

 

Thanks for posting those, John.

Wow, what a maze ! I really hope not to have to take my SL apart like that someday, but we all know eventually....

Fiber Optic Loom '78 450SL

The fan-shaped fiber optic loom for the dashboard switch lighting is on the back of the ACCII control panel in the console. One lead will go to each switch. On some cars, the loom (or spider) is located toward the firewall, behind the A/C controls. One bulb lights all of the fiber optics. Often, especially if the radio has been replaced, the fiber optic leads are pulled out of the dashboard switches and may be found laying behind the A/C control panel. In the photo below, one F/O lead is snapped into place, and the remaining slots are vacant for illustration.

A photo of the "spider" style F/O connection on the firewall is at http://www.benzworld.org/forums/r-c107-sl-slc-class/1569615-need-help.html#post4572460

1985 500SL fuel pump relay

Behind the glove box on the right side deep in the back. But it was quite easy to pull out. Just unplugged.

Sorry for the shaky pics, it was dark and close quarters in there so the camera shutter held open for a while.
