BMW e36 Crash Alarm Relay Replacement ('98 M3)

e36 BMW Crash Alarm Relay Replacement on a 1998 M3 US spec.
Symptoms of a bad Crash Alarm Relay:
-Dome lights and foot well lights turn on
-Flashers are activated
-If car is at idle you can notice what seems like the car being choked of fuel (revs drop by a few hundred)
-Airbag light is on (dashboard)
I found a Crash Alarm Relay on ebay for $20. Brand new they run $40-$50.
