Couldn't find a wiring diagram... anybody know what 1,2,3,4,5 control?
Based on the one I pulled in the yard:
1: +12v instrument lights
2: Connection w/3 & 4 in up position
3: Connection w/2 at rest
4: (see 2)
On my 124 I installed this switch and its harness / socket in place of the fader (running a replacement radio & wiring). However it isn't wired yet.
Thanks look forward to the result!chabanais,
It appears that MB used multiple variants of this switch / wiring. The results I posted are based on testing the one I have with an ohm meter and 12 volt battery. Hope to have it connected tomorrow, stay tuned.
