Questions on hooking up DRL's in 2014 RAM (USA model).

[dpinvidic]

I have some aftermarket LED DRL's. Three wire hook-up (Gnd, Ign, Signal).
I read in another thread that the LED turn signals on the truck only have one wire. They apply 3-4V for running light level, and bump it to 12V when they engage the turn signal. Can anyone confirm this?

ALSO, is there an easy place to pick up a ignition connection (key on).

This new truck wiring is a lot more tricky that when we just had a 1034 brake light bulb and no CAN Bus.

Thanks,

Dan
