Relay board to starter Options

[last337]

First off this is a '73 model.

I have been going over the wiring diagram for harness plug going from relay board to starter. I pulled the plug apart and for some reason the #6 post (yellow) is cut going into loom and there is no slip connector inside the plug. Now I know I didnt remove that connector from inside the plug but I cant recall if that yellow wire going into the loom (that goes to 50 side of starter) was cut when the tin/starter/etc was all removed. I checked voltage for that post on the plug and get .45v with key in on position and only slightly higher .50v in start position. I dont have a current meter so I cant tell what the amps are at each key position. Looking at the actual post itself it appears someone at one time soldered to post #6 (see pic) but there is nothing there now. I really wish I could recall what it looked like before but that was 2 years ago and I dont even know if I was the one that pulled those connectors off.

Is it possible that there is another post/spot that could have been used to fire the starter? What should I check to ensure that post #6 is doing what it should do when key is turned to 'start' position? I have been going all through the diagrams but just cant imagine how else the starter would engage.
