Hello all I would say GO FOR IT!!
It is totally worth it ,because in the end you will have a brand new game ,don’t worry about time spending because in the bottom line you are learning new skills how to make something from scratch .
Since 2016 I have build Twilight zone,Tales of the arabian nights and now Addams family gold.
In regards for the wiring you can remake it with the exsact color code just find a game wiring from wpc 89 or 95.
Any part I can’t find second hand I remake it ,and if I’m lucky to find used ones on eBay that works even better.
If you build your own game it will cost you less money plus it is a legacy to pass on to your family since it will be much more appreciated because you give it life !!
If you need help here I am knowledge is free as long as you use it for good cause .
