Sorry to resurrect this, but I think it’s worthwhile. I just wired in a power supply using the above instructions (thanks!). Measures 13v DC at my available plug. But I’m hoping to use it for my colordmd which seems to be taxing the system. I notice the colordmd plug has three wires where my supply only has two outputs. Is one a ground? How do I wire it to power the lcd?
Thanks
