PCV AutoTune K1200GT hot wire

I've installed the PCV with autotune on my 2007 K12GT, but the Autotune is having issues.
I tapped into the tail light wire to power the autotune, but it's as if it's not getting the power it needs to run. I don't want to run wire direct to the battery, because I want it only one when the bike is running. Has anyone else had this issue? Or has anyone fixed the issue?
I have been searching the internet for weeks, but I haven't been able to find anything.

Please help!

tail light is pulsed which means it is not at 12 volts, but about 8-9 volts mean
when brakes are activated it is no longer pulsed i.e. now 12 volts, as the brake light
higher voltage, brighter light

tap off the front running lights, they are always 12 volts

Try powering the autotune via a relay. Relay power from the battery and switched via the taillight wire. That way it will have a full 12v and be switched with the ignition.
