Received the harness on Monday and the LEDs from Diode Dyanmics today. Installed this afternoon and everything works as advertised.
Just like
@Tenscourts in the video, I used 3M double sided tape to attach the resistors rather than drilling holes in the metal. The hardest part was pulling out the existing harness connectors, they were stuck pretty good!!
Between the harness and LEDs it’s a ~$400 mod so definitely not cheap but for me worth it. I’m hoping spending the extra $$ on quality LEDs will pay off long term and they will last a long time.
Thanks Tenscourts and everyone else in this thread for all the tips and info!
