I just installed a TOD on/off switch and my TOD display lights up whether the TOD is on or not. This is because I have the cable from the TOD ECU going to a 20 ohm resistor to trick the TOD ECU into thinking that it's connected and not give a bunch of error lights. Apparently, the electronics that operate the TOD lights come from the TOD ECU and not the TOD clutch or solenoid. So the TOD display is telling you how much power the TOD ECU is sending, not how much is acctually getting there.

First, as has been suggested, look for an unmarked switch. I can't feel any difference when mine is switched, so you may not be able to tell what it does right away. Maybe take it off road.

Second, take out your passenger seat and look at the electronic thing that looks like a small amp. That's the TOD ECU. If the light blue wire that is coming out of it has been diverted, then that is your issue. You either need to reattach it or connect it to a switch. I would recommend the switch assuming that it was diverted, in the first place, for a reason.
