Quoted from frunch:For female connectors: Make sure to get keying pins for 0.156" housings, 0.156" housings for the new connectors, and be sure to get the 0.156" trifurcon connector pins for both larger and smaller gauge wiring. (They have 18-20ga for larger wiring, and 22-26ga for thinner wires)
Get regular non-trifurcon .156's also, they're not really needed everywhere, and the 20 pin display connectors are REALLY hard to pull off when they are all trifurcons. Also you can't use trifurcons on edge connectors if you do gottlieb or williams games.
