I am new to the forums and I have been browsing through the SimHub GitHub article on the "BMW E36 Cluster Setup". I understand that it states that there is no support available, but I was hoping to find information on how others managed to supply power to the 12V pins. I came across another article that is linked on the page, (Arduino After Market Tach support) and I am not sure how to apply it to the BMW gauges. If anyone could provide me with a wiring diagram or guide me in the right direction, I would greatly appreciate it. Thanks in advance.
