IDK the voltage, but I know this; on the ZJs with a BCM, it's pulse-width modulated.

I'm going to install a VIC today so I'll put a meter on the ash tray light. It is on the same circuit as the inst lights.

Ok, take me to school on that one. I think the WJ heater or radiator fan is pulse width modulated. I take that to mean that rather than a constant voltage it is pulsed at varying band widths to maintain speed, light intensity. I assume its a more definitive way of fine tuning output? IDK.

i have no idea why they would modulate a lamp voltage, but it must be VHF because the meter reads battery voltage on the orange wire to the lighter halo.

yes, it worked like a charm. And it exhibited behavior I never noticed on the first one. when i press a button with the key off, it shows the time and date for a few seconds. I swear my old one didnt do that.

OK here comes the freaky part. I spent pretty much the whole day cleaning mine,inside and out. I was finally about done and was using a plastic screen wipe to clean the VIC screen and pushed a button while doing it. It did the same thing and I had never seen that before either,lol. Didn't know Chrysler had a subliminal function included.

i guess they thought you may be sitting somewhere without your keys and need to know the time and date.
