AOD Neutral Safety Switch
I just put an AOD behind my 302, I have a column from a 79
Cadilac, and I am wondering how to wire up the Neutral safety switch. Can anyone give me some quick instuctions? All of this is going into a 1954 F100, with a painless fuse panel.

AOD Neutral Safety Switch
Did you install the AOD or did you have someone do it? It should have instructions if you did it. If a tranny shop did it, they should know. Worse comes to worse, contact the manufacturer of the AOD for pointers or instructions with your column.
I had an AOD put behind my "bully" 302. The shop that installed it hooked it all up with no problems.

AOD Neutral Safety Switch
The AOD nsw is located on the top left of trans,it has 4 [if my memory is correct] male plugs. Two are backup lite, other two are neutral safety. With trans in rev, backup should be hot[when feed with 12v] with trans in park or neutral, both nsw plugs will be hot. Hope that makes sense, it worked for me.

AOD Neutral Safety Switch
I'm not exactly sure what you specifically are asking, but here are my comments. You mentioned installing your steering column. I personally wouldn't attempt to use the neutral safety and back up light switches that may be present on the Caddy column. If you have a linkage misalignment or failure, the possibility that that truck could be started in neutral exists. The switches on the AOD are nearly foolproof and probably more reliable. For the backup lights, you'll need to tap a hot feed from the ignition switch and bring it down to one of the backup light switch terminals on the trans. Then carry the switched voltage from the other terminal on the switch back to the lights. For the neutral safety switch, carry the solenoid trigger wire from the start terminal on the ignition switch down to one terminal on the neutral safety switch and then run the wire from the other neutral safety terminal to the trigger terminal on the starter solenoid. This way the neutral safety switch can interrupt the ignition switch signal if the truck is not in neutral or park.
