Pathofinder, you do not want to remove the air bag light, you want to diagnose what is up with it. That can be done with no tools by using the door switch etc. but you'll have to read and follow the procedure(s) in your specific manual. But since you are having a whole lot of problems from the PO or the previous owner's mechanized butcher you should do what you are doing. Find out what and where you stand with the butchery of the electrics.
With that removed plug still dangling out of socket, with a 12 V voltmeter ground the one lead to the car's negative ground and with the other lead try the poles on the plug to verify that as it sits that plug is dead on all poles, then redo this with the other plug. One of the poles on either plug should come alive 5-12V with both plugs still apart.
The plug that is alive will be the feed. Then you can go on from there. If in any attempt to use a jumper cable and you want to start jumping things out use a jumper cable with a 5 A fuse in line. That 5 a fuse will protect things that should not be shorted and/or jumped. The use of the electrical pull out sheets with schematic should help, be sure to use the EL section and the restraint section...you may have to interpolate the drawings to and between sections.
Mount the fuse into an enclosed fuse holder with 2 pigtails and install the fuse holder in series with your jumper. If and when the fuse blows it will protect you from a burn, a self indicating type of fast blow fuse would be helpful in letting you know that the fuse has blown otherwise a blown fuse will make the jumper not a jumper.
Before closing that plug verify what you have.
And remember to record what you do DO NOT RELY ON YOUR MEMORY.
