Great work you're doing there! I had a TM and we had a lot of fun with the callouts and chimes. Kids loved it.

Quoted from gdonovan:

So where is a good vendor to obtain connectors and pins? I assume they are standard as they look like others I have seen. PBResource carry them?

Great Plains Electronics, hands down, no question: https://www.greatplainselectronics.com/categories.asp?cat=35

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).

Quoted from gdonovan:

Great Plains is closed for vacation! ha!
Order to pinballwizard is in- power supply, elastics, "laser kick" coil and parts for laser kick. The plunger came apart no problem but is missing the nylon tip so just ordered the whole kit.

DOH! PinballLife.com has most of that stuff, probably everything you need: https://www.pinballlife.com/molex-crimp-stuff-connectors-and-parts.html

.156" is what you need to look for... they even have the "key" filler piece: https://www.pinballlife.com/156-polarizing-key-for-molex-crimp-stuff-housings.html

Have fun with the socketing! I hope you have a nice hakko desoldering gun!

Quoted from gdonovan:

Nope.
Chips are so cheap no need to save them. Just cut the legs off and desolder one at a time.

It was more a concern of any through hole connectors, don't know if those have any. I wanted to do NVRAM but don't have a desoldering gun and I hate doing it manually. The sucker pumps only work so well and don't get me started on braid.
