Hi Ray! Thank you for the kind words, much appreciated! I have had some set backs since my last update, but hope to get going again on some progress soon!
Nothing beats working on a G503! I was torn on whether to buy a wiring harness or build my own. A purchased one would be the most factory accurate I believe, and they are excellent quality at a fair price. Last month before I paused work, I started to make my own harness because I wanted to better understand the wiring. I figure the best way to know it inside and out, is to assemble it hands on! I already made the headlight harnesses, but have some finishing details to work out and add.
Hope to update more here soon! Thank you again for your interest!
