Default New wiring harness issues

I am trying to rewire a 1973 International Scout II with a 304 engine. Someone cut out the bulkhead connector and hardwired the dash to the engine. I am having issues with the new harness not matching up to what I believe is the correct pinout/configuration of the harness. I have a couple of connectors on the harness that do not match what is on the vehicle. To the best that I can tell, the new harness DOES match the schematics I've found. Did Inter. happen to put parts from other vehicles that could be made to work on these?

Edit - I found that a dash connector looks different from the schematic for the neutral safety switch. On the schematic it shows a 3 blade connector where I only have a two blade connector specifically for the switch with the old harness. I have a two blade connector for the new harness as well, but the alternator is attached to it too. I seem to have a separate wire/connector to the dash for the charging gauge.

Is this a brand new harness or from another vehicle?

Brand new. The part number is SP2123531 71-73 Scout II Engine harness. I would like to add that I did get the firewall connector, both halves.

Ok, so you need to connect a new engine harness to the existing cab harness. Is the old bulkhead connector completely gone from the cab harness? It sounds from your question that it might still there.

I have a new bulkhead connector for both sides. It was taken out and the engine was hard wired to the dash harness with twist and tape splices.

I need help finding the physical wires for circuits 71 and 71A on the dash side of the bulkhead connector for the neutral safety switch and figure out the connector difference for the wire to the alternator gauge.
