If working on your airbag-equiped wheel looks intimidating, study and research the procedure in the Bentley manual until you feel comfortable. Most importantly, disconnect the negative terminal from the battery and wait at least 10 minutes for capacitors to discharge before beginning work. 7) Prepare the horn and airbag connectors by splicing common electrical terminals on each end. Cut off these connectors and splice in common electrical connectors. Check that SRS warning light turns off and horn is functional. (cars using slip ring '804): These cars use a slightly different stock slip ring (airbag connectors are different from 92-93 but same as '95-on).
The procedure is the same as above, omitting airbag wire splicing (most of steps 6-9). (cars using slip ring '111): You guys have it easy.
This should be a direct plug-in job, not even requiring a steering column switch bracket.
As long you're already using slip ring '111, follow procedure above but omit steps 6-12.
For those tired of staring at their old and ugly airbag wheels, there is a solution: retrofit a new sport or stock airbag wheel with the BMW roundel badge!
This procedure applies mainly to E36's without badged airbags but is applicable to all BMW's from 7/90-3/99 (meaning all 3/5/6/7/8 series). They are NOT recommended for earlier cars (although it's been attempted).
For those with badged airbags ('95-on, except M3) who just want to retrofit a sport wheel, the procedure is very simple. If re-using old slip ring, verify it's centered (it should turn no more than 2.5 revolutions in each direction).
With these cars (build date of 9/94 or later using slip ring '111) it should be a direct bolt-on/plug-in process. 11) Back in the car, remove column switches from bracket. Secure slip ring to back of wheel with the small screws (see image above left). See that slip ring locks into pin on steering column switch bracket.
92-94 cars and all M3's use two other slip ring part numbers (either '901 or '804) which necessitates simple wire splicing to make the new slip ring compatible with the car's wiring. Release underside screw and remove column switch bracket. 14) Connect yellow airbag plug and brown horn connector to back of airbag. NOTE: Due to the way the airbag plug is made, it may disconnect itself when you push airbag into position if the wires press against the plastic warning label inside wheel.
The steering column switch bracket (p/n above), which holds the column switches, will also need to be changed to comply with this newer slip ring -- a very minor task. 12) Release slip ring pin from old bracket and insert in new bracket. Check that airbag plug wires are routed outside warning label and are free to move, or remove warning label entirely.
