I think Painless leaves out one wire. Pay attention to the IGN1 (ignition run) and IGN2 (coil bypass) which is missing I think. If you read that wiring pdf which I created from the original manual, there's charts on past the diagrams which show the various connectors including the ignition switch connector

S2. 12Yellow is start--feeds off through the firewall connector to your start relay
Q2 12BlacK is the main feed going off to the fuse panel ACCESSORY buss
J2A-12Dark BLue is the "ignition run" goes out to engine bay and feeds ignition system. THIS IS LIKELY different with Painless I think they have a separate wire for "alternator exciter"
J3-12Brown is the ign2 coil bypass circuit. If you are NOT using an ignition with a coil resistor, using such as MSD etc, jumper the J2 and J3 together THIS IS likely the missing wire with Painless not sure
J1-12Red is the main feed power coming INTO the switch
E2-20 Orange May or may not be used. This is dash dimmer controlled panel lighting going to the shift quadrant if column shift
M16-20BlacK
M16A-20BlacK These are the "key in" switch mechanism for the little "key" light and buzzer
