Need some help on ignition wiring

[cs69er]

I'm just about finished wiring my cr cobra with a Painless wiring setup and it has gone better than my fears initially thought. I bought a steering column from DV (and it is so smoothe! Thanks DV) but the column does not have the key on the column . The ignition switch I purchased has 4 lugs on it. The 3 outer lugs are labeled ACC, Ign, Bat and the center post lug has no label. Is the center post a ground? The wiring kit also has 2 plug boxes that I assume plugged into the old column for the ignition. The first box has 2 wires , one red and one orange. The second box has 4 wires in it, red, pink, brown and purple #919 which is for the neutral switch. Unlike all the other Painless wires, these wires have no numbers on them except purple #919. Any ideas on wiring up this ignition switch?

Also, DV, which Lokar shifter are you using for your automatic setups? I down to setting up the transmission shifter and building the brake setup and drive shaft. It looks like I have timed this construction project well with about 3 weeks before the schools start back up and I'm just about finished with all but the paint job. Oh to have the body painted by then!
Thanks to all the great advice to my specific questions and all the other advice I have gleemed from this forum. Chuck
