alright i have a 95' tacoma 4x4 5spd ext. cab and there is a 3 way switch mounted on the left hand side of the steering wheel, anyways theres 2 wires leading from it. one goes to the battery positive post and the other goes to a vacuum/sensor of some kind. the sensor i think is located on the driver side just next to the fuse box. when i flip the switch up it makes a sudden jerk as if the front differential is engaging then makes a vibration/grinding type of noise. i just need to know what this does it pretty annoying.
thanks,
Rodney
