Is the reverse switch hooked up? If the truck is an automatice or 3 speed manual the switch should be on the column. For a 4 speed I believe it is on the transmission.

You can take the wires off the switch and with a test light you should have power to one side of the switch. If you do, then use a jumper wire and put power across and eliminate the switch, and if they work now you probably have a bad switch.
