I can’t say anything about the airbag itself (the TATA recall thing) - from memory the inertia trigger for the airbags “lives” on the tranny tunnel forward of the shifter.
IIRC, it’s a weighted /metal ball bearing that shoved forward under force completes the circuit, but hopefully someone else will ‘tag in’ & confirm as I have alot of BMW E36 platform stuff in my head & I had it all ‘blended together’ in that concussion I took.
@Tools R Us — Kevin, how about maybe you correct or confirm my info?
As for airbag connectors, I personally don’t see how using quality insulated male & female plugs you can’t mix-up would hurt.
Or, ideally - de-pinning the wrong connector & re-use the right one, since I’d bet the terminals themselves would be near universal (just an idea, I have de-pinned multiplugs before though so to me it isn’t a new thing).
