Hi all, I'm getting the typical airbag passenger restraint 93C3 code and not quite understanding what else I need to do here to clear the code.

I think I may need to connect the wires for the seat belt chime.
I connected the bypass sensor to the rear of the seat and cleared the code but it keeps coming back.

I think I need to bypass the front harness as well but unclear on these directions. This is a 2011 E93 M3. My apologies if this is in the wrong section and I did search but didn't find exact wiring for the seat belt chime wires.

Thanks all and greatly appreciate any help!

(Edited to add that I uploaded the pictures in the right way but unsure why they are not vertical :confused2)
