That blog post is extremely useful and what I used.
I do remember some finagling with the wires to figure out what's what. 3 to the beam. 1 if extra if it had a parking lamp.
Struggle I had was having blinker pods on as day lights without main headlight being on. On top of that since headlights have a DRL beam that also had to be connected to same power source.
I did utilize the headlight as part of blinker where DRL turns amber, I left that feature off. Seemed redundant with pods. If I wanted to not use pods, it's a perfect feature
I have some pictures but it's hard to tell at what part of the process they were taken.
Power probe made things ALOT easier
