OK I'm putting an old radio in a new truck and the wiring harness
had to be slightly different. Bottom line: I've got about 5 extra wires
coming out of the radio. Now one of them powers the panel lights but I
don't
know which one or how much power it needs. How would someone go about
'tickling' the wires with increasing voltage (up to 12 one supposes but
maybe less?) to determine which one controls lighting?

Keep in mind that in new vehicles everything talks to the control module.
If you want the window down, the switch doesn't put the window down it
tells the module that you want the window down.
If the module thinks you should have the window down, it will do it. The
radio is no exception. You may have speed sensing sound, alarm tones and
more.
Get an adaptor.

An old radio wouldn't have that capability...

There are likely leads for:
power (memory)
switched power
dial lights
speakers (x4)
antenna in
antenna motor
ground (x5)
