Early '02 (9-01), 4.7, 2WD. No turn signals. Turn signal switch ON either way, dash indicators and audible click flash rapidly like a bulb is out. No current to any of the sockets, front or rear. Fuses good, bulbs good.

Any wiring diagrams or information I look up on-line do not match this truck. Not even close. I could figure this out if I had decent information. Anything common that causes this? Good source for correct diagrams?
