I have a 1989 Toyota 4x4 V-6 and ever since I got it back from having a new cylinder head put on, the 4x4 doesn't work. The front drive shaft and axles lock in when I put it in 4H or 4L but the indicator light doesn't come on and the front tires don't spin (except for the free-wheeling action you get in 2 wheel drive.)

There is a wiring harness that runs down to the trans/transfer case, make sure everything is plugged in . Maybe a connector was forgotten or accidentally unplugged

Inspect the wiring harness running to the transmission and transfer case, and confirm every connector is fully plugged in. A connector may have been left disconnected during the cylinder head repair.
