reinstalling w126 cluster SRS/ABS/SEATBELT warning light locations?
 
I'm putting my cluster back in with all new bulbs.
there are 3 warning lamps on the right hand side- SRS, SEATBELTS and AIRBAG which are not part of the cluster's integral PCBoard. The bulbs have their own separate harness and just sit inside their housings. I have no idea the orientation they should go. They all light up when the key is on, 2 go off but one last stays on when the engine is running and I would like to know which one it is before I pull the bulb and forget about it.

The wire colors are
black with reddish stripe and
pinkish/orangish (I'm colorblind so that's as close as I can get)

for what it's worth, the ABS system worked on the ice yesterday so if I were to guess by elimination, it's probably the air bag light or seat belt light staying on all the time. Is there another way to check?

According to the diagrams on my MB disks...

Seatbelt light only has 1 wire - Green/black
Anti lock brakes have 2 wires - Black/Red and Brown/Yellow
SRS has 2 wires - Black/Red and Pink

Even if you're color blind it shouldn't be too hard to fix. The seatbelt light only has 1 wire and will be easy to indentify. Antilock will have 2 striped wires, SRS will have 1 striped and 1 solid color wire.

Hope this helps.

That definitely clarifies things. Thank you- It's the Airbag light.

Strange, it wasn't on before it all started coming apart and I didn't disrupt any of the airbag harness. The driver's seat belt harness was damaged recently when I replaced the seat spring and is disconnected. Can that be causing the code?

Any advise on how to reset or test diagnose this early SRS system?
