No SRS light at all
 

Hi,

I posted this on Benzworld, but maybe not everyone is reading both...

Car: 1992 300D with om603 swap.

When I start my car or put in ignition on, the SRS light doesn't light at all. Even with engine off and ignition on.
When I plug the code reader to 1 & 6, I get light all the time on the LED.
I replaced the lightbulb in the instrument cluster twice. No change.
Connection under driver's seat is ok.
Where should I look? Seems like there is no power to SRS module at all?

Thanks,
Filip

PS. Yes, I replaced the OVP with a known good one, no change.
