Type B Switch Test
Use the meter or test light to find a point on the fuse block that pro- vides a constant source of +12 volts. Touch one lead to that point on the fuse block, and the other lead to one of the control wires. Operate your power door locks.
If the light turns on or the volt meter indicates 12 volts when you move the door lock switch to the LOCK position, you have located a Type B Lock control wire. Test the other wire.
If the light turns on or the volt meter indicates 12 volts when you move the door lock switch to the UNLOCK position, you have located a Type B Unlock control wire. Test the other wire (if you have not already done so).
If both wires are Type B control wires, go to Step 3.
