E83 Window Regulator replacement question - airbag light?

[ButtDyno]

I'm replacing the window regulators on a 2004 X3.

Following these instructions:

My question - do I need to put the door panel back on (or at least connect the airbag) in order to avoid a permanent airbag light?

Or can I hook the power back up, leave the door panel off, possibly get an airbag light, test the window, and then put the door panel back on once I know everything works and the airbag light will clear itself when the door panel is back?

Thank you!

When I had the airbag light and functioning problem.
Once I discovered the true problem...First I made sure I waited 30min or so after I disconnected the battery BEFORE I started any dismantling. When I got to the panel the airbag (using a pocket flat head) connector had to be lifted from the front and the back... Believe it or not there is a proper way of (search newtis) disconnecting... If broken... the tab (called squib) will not allow the airbag to function and a dash light will illuminate... this broken tab is ofterned over looked and leads to misinterpreting the error.

Anytime I've replaced window regulators, I've used an external 12V power supply to run the mechanism up/down when things are still apart. If you have one, it makes the job easy without the fear for the airbag light.
