4 wheel drive wont engage
The differential is not engaging and the light on the floor board does not come on when I shift into 4WD on my 1989 silverado. There are two sets of wiring harnesses going into the differential. The upper has 3 wires and the one on the bottom has 2. I checked the fuse and its fine. Do both sets of wires go to solonoids inside the differential?

The 2 wire connection is power to the actuator, the 3 wire goes to a contact switch that turns the light on. Check for power on the 2 wire when you have it shifted into 4wd, remember to drive a little after you shift to give it a chance to engage.
