Thought I'd post this as well. It's an LCD touchscreen controller for the chassis wiring harness. On the right in the video is a 12v relay block that is controlled entirely by the touchscreen and that postage-stamp sized chip with the blue light on it. No laptop required!
Pretty proud of this thing so far. I need to finish my circuit design for the fuse/controller board, but all the artwork and programming are done. Won't be long now!
