I'll say search "j.belknap" post where he taps the park-light from the LCM module by the front passenger foot-rest area. You still need to feed this line to a automotive relay just to be on the safe side (not overloading any LCM circuit).
The advantage:
- no flicker when AE is off (like you have now)
- no flashing with turning signal
- brighter, cause right now that park light is only powered about 6V then when turning signal is flashing it'll alternate between 12V and 6V.
