Hard to say based on various skill level. I could do it now without fear or worry very fast. When I first started pinball it all seemed super complex and scary. Things can go wrong if you mix wire plugs. You could blow a board. If you label everything and double check with photos you should be good. Basically anyone with patience could do it. Not something to get in a hurry with. I’ve included a picture of a wire harness for the head of an EBD. The person I bought the game from had to throw in the towel. I actually enjoyed putting it all back together and tested. I would say go for it and learn something new!
