Yes I have the blanks for them. I went a bit overboard and got like 400 total connectors in the various combinations of end/thru 18/22 100/156. Average cost something like 35-40 cents each when many were $2+ on Marco. I'll have plenty left over when I'm done to resell if anybody is interested.
I think I'm just going to replace every IDC on my game. I'm finding several mismatches. Thru connectors used where end should have been. Some red where orange should have been and vice versa. Plus some mixed in molex connectors where wires were spliced and run to multiple pins in place of IDC thru connectors. Overall it's quite the mess.
Spent 4 days last week replacing every switch and target. Should get my playfield back from HSA in another week or so. If/when I finish this thing, I'll make a long post with details of all I did. I think I'm approaching $11k in total costs now, but this is the first time I've done anything like this and it's a blast learning how this all works.
