    so I have a 1990 ext cab. Currently trying to figure out if the turn signals and running lights work off a 12v switch or is the ground switched. When I put the meter on them. They both show a ground but when I turn the turn signal on one holds a ground and the other will jump from 5 volts back to ground. And input is appreciated. Thanks in advance.
