Thanks for posting this. It's the exact configuration I have. Additional questions:
I tested the LED harness plugged in both before and after the sequential turn signal harness. Both worked, so I settled on before.
I've only seen the LED strip turn on momentaily (~30s?) after pressing the lock/unlock buttons on the remote fob. Possible it may turn on at other times but it's hard to tell from the driver's seat. Sometimes I can see the reflection of my car in the shiny bumper of a truck or van, via the rear view mirror. The LED strip doesn't appear to stay on when driving, regardless of the position of the light switch.
1- any combination is fine, no difference.
2 - LED strip connected to tail lights (parking light), so it will light up whenever parking lights are on.
