The bulb could be burned out, which would be the simple explanation, or there could be a worn-through wire to the solenoid on the transmission. As far as I know, the solenoid always has power, unless the OD switch turns off the power.
Maybe someone else can answer this, or has a wiring diagram handy.
Good Luck, and the quick test for the kickdown cable is simply to remove it from the throttle spool and secure it where it won't catch on anything (a simple twist tie would work fine for that. While it's disconnected, if you want to downshift, you'll have to do it manually.
