You don't wanna unplug anything having to do with the airbag system. The computer monitors every sensor in the system and if it sees something wrong with any of them, your SRS light will be on all the time and the only way to get it to go off is by taking it to the dealership, bring Vasoline and a pillow to bite. I'm not 100% sure on this, but the computer may disable all the airbags until the problem it sees goes away.
But FYI, any plug in the car having to do with the airbag system will be yellow. Yellow plugs are airbag system plugs.
