Are you talking about the lugs on the EOS switches?
If so, it doesn't matter which way around the wires are on the switches... they are just contact switches with no diodes attached to them, so wither way around will work.
Yes, just the lugs on the EOS switches. Previously both wires were going to one lug. I could not find any documentation to let me know how they were supposed to be wired. I found a pic on Marvin's site for a D.E and I followed the colours as they had.....BUT if I manually open the EOS switch , flipper will not operate...If this is not suppose to happen then I may have an issue...
