Quoted from gdonovan:Pardon my ignorance, what should I be ordering? Or should I just wait as Allentown is next week?
To replace the plugs you need a few parts:
1. Plug - choose the right plug to fit the one you are replacing (https://www.greatplainselectronics.com/products.asp?cat=81, scroll down starting with "Connector, 0.156" Plug, 2 Pin") and choose as many pins as you need. Get a few of each, just in case. I'd probably get these https://www.greatplainselectronics.com/proddetail.asp?prod=08-52-0125&cat=81 and https://www.greatplainselectronics.com/proddetail.asp?prod=08-52-0072&cat=81
2. Crimp Contact - I don't know why you'd choose one over the other (which material), but you should match your wire size. I'd get a bunch for each wire size just in case, they are cheap. (https://www.greatplainselectronics.com/products.asp?cat=81 starting at the top)
3. Crimper - You'll need a wire crimper, I have a special one for crimp contacts but as long as you have something like this (https://www.greatplainselectronics.com/proddetail.asp?prod=CT-4071-1R) you'll be set.
4. Keying plug - They are out of stock but it's a good idea to key them if possible (https://www.greatplainselectronics.com/proddetail.asp?prod=15-04-0219)
If you've never done it before get a bunch of extra crimp contacts.
If you need to replace the header on the board then you'll have to desolder and put on a new header:
5. Headers - https://www.greatplainselectronics.com/proddetail.asp?prod=26-48-1245 you can cut them to suit your needs
There are probably a ton of youtube tutorials out there as this isn't pinball specific. Biggest keys are that you crimp properly (half on the bare wire, half on the insulation), insert the crimp contacts into the plug the right way (easy to see once you do it) and match wire for wire (I do one wire at a time).
