I forgot the year model for this car, but I always found the w123 Electrical
Troubleshooting Manuals (ETM) to be excellent.
Try here:
https://www.startekinfo.com/StarTek/outside/12265/disc_2/program/ETM/80_240.
pdf
Or here:
https://www.startekinfo.com/StarTek/outside/12265/?requestedDocId=12265
And walk step through the menus to the ETM for the correct year model.

Subject: Re: [MBZ] 123 weirdness
Ground seems to be the only commonality for windows, gauges but not turn
signals, as those are grounded at the 4 corners I think
On the 124, the windows are grounded under the tunnel, near the gearshift.
I
don't know where the ground for 123 windows may be.
I've never scrapped a 123, so I am at a bit of a disadvantage.

at 6:42 PM Ground? I had the fuel and temp gauges quit because of a
cluster ground. They'd bounce forlornly when the blinkers were on
leading me to believe theres some grounding commonality there...

Subject: [MBZ] 123 weirdness
took the 81 240D (123.123.12) out of winter storage a few days ago.
Fired as soon is one jug hit the compression stroke.
Driving round today, I saw the fuel and temp gauges quit working. As I
went about my errends, some 60 miles, I kept jiggling the key, but the
gauges stayed dead. The windows are also dead, as are the turn signals,
or at least the indicator. Since I did not hear the clicking, I believe
the signals are dead too.
The dome light and radio (and antenna) work.
At first I thought it was a bad switch, but no amount of off/on or
wiggling has restored function. If the Aux wire came loose at the
starter, I should not have anything working, including the starter
solenoid.
Anyone BTDT?
Anyone got the schematic handy?
Am am wondering if a screw/wire came out on the back of the ign switch.
Beyond that, I am not sure what feeds the cluster windows and blinker.
Obviously, Clay should send me dome of the mystical M1 blinker fluid,
so I can change and refill it.
BTW, it runs great and 4 segments of ~10 miles or so eye-tal-yun tuneup
were good for it.
