Sorry for the delay. Please let me know if I missed anything.

@TheW3r3W0lf, could you elaborate on installing the 50ohm transistors as to how you wire those in at the junction of the parking light. I'm very proficient in 12V as I am an MECP, however for some reason this was confusing to me. If anyone else can elaborate, that would be most appreciated.
Thanks.

So after some intense reading and research, would you not be able to wire the Transistor instead of going from negative on the parking lamp / drl harness, be able to route that black wire to the ground of the body using a ring terminal, and still wire the red to the positive of the turn circuit? If this would work , i'm pulling this in combination of the other DIY which talks about using the RELAY , which by the way is really nice as well. I'm just thinking about the 12V aspect, and figured you could wire this either way. Just curious if anyone can shed some light. I have now answered my question above about how this installs correctly.

LEDs have a higher resistance than incandescent lamps. Higher resistance means less current. The BCM sees this current drop and assumes the bulbs are burnt out. Placing the resistor in parallel reduces the resistance of the circuit and gets the current back up to where the BCM is happy.

That'll work. All you need to do is put the resistor in parallel with the LED. Since one side of the LED is grounded, you can ground one end of the resistor.

Wolf, how is everything holding up? I'm looking to do this next month.
