Automatic trans harness in a manual trans truck?

[straight-shot]

I am putting my truck back together after paint and am running into a problem with my wiring harness. The truck is a 1970 f250 hiboy with a 4 speed manual transmission.
I am using parts form a 1970 f250 2Wheel drive truck. The harness in the 4x4 manual was a little rough so I was going to use the nicer 2wd auto harness instead. Now that I have the 2wd harness in the truck I didn't think about the neutral safety switch. I have found through search that you can jump the neutral safety so it will start in any gear but I will lose my back up lights or have to wire them into a switch.

The 4wd manual harness has a two wire connector on the driver side firewall that runs to the top of the transmission. The 2wd harness has the same two wire connector but has a jumper that connects the two.

I Have two questions:
#1 On the 2wd auto harness Can I jump the neutral safety switch across and plug from the firewall to the two wire connector to the transmission to make it all work?
#2 Can I use the Manual column and wiring with the automatic harness without too much trouble?

Thanks!

There's a four flat connection with wiring pigtail that gets swapped out between auto and manual. Wire colors are the same red/blue is the start ckt, the black/red is reverse. Check the factory wiring schematics under the main site for more details.

Just extend the reverse wires to your switch. If memory serves some of the switches had threaded terminals that the factory connector slid over.
