Installing my new Blueprint 408 in the 72 Duster. All the wiring from the firewall forward I replaced with new harness from Classic Industries. My questions are. What are the two pictured connectors used for. One is coming from the wiper harness. The second is part of the lightning harness. The last is what is the purpose of the second blue wire with connector coming from the alternator. I have a flat back style alternator with electronic regulator . I’m replacing the factory automatic with a 4 speed. Thanks for any help.

Can't tell from your pictures, but you should have two purple wires from the wiper section that go to 4-sp neutral switch.
 
top pic plugs to the trans harness for reverse lights. for 4 spd . for automatic the harness that plugs to that has a third wire that goes to starter relay for neutral safety

Second pic if from alternator is for, Ignition resister unless the harness you have is for electronic ign., Or could be choke thermostat on intake

Both sets of wires are black and black/white tracer. Do I need/how to bypass for clutch/neutral safety for startup? Thanks

Those two wires only operate the reverse lights. The harness you attach will determine the clutch pedal or neutral safety switch application. Those two wires if connected will turn the reverse lights on. The trans switch does that.
 
I’m currently using a ready to run distributor so I eliminated the ballast and wired those together.
I don’t have any kind of clutch switch. I sold the 727 out of it. I’m thinking the harness that went to transmission may have gone with it? Here is the starter relay. Will something need to be grounded for the car to start if there’s nothing coming from the clutch pedal?

There is a plug in front of the yellow wire plugged on the relay . Ground that terminal to the bolt holding the relay on . Prior years the relays were 4 spd. specific and the terminal was bent over and crimped to the relay housing. Only the automatics used the forward terminal.

When they started installing clutch pedal switches they used the same plug on the relay for that switch from the pedal. I always eliminate the pedal switch on my cars. Just in case you need the starter to move the car off the road when the engine dies.

I already drove my Omni to the gas station with the starter. My friend held the key on while I shifted. You wouldn't believe how fast you can go on the starter.
 
The blue wire you can eliminate with a ready to run and a non electric choke carb. If your carb has an electric choke that's the wire to use. I just looked your carb is mechanical choke. So you don't need the wire.
 
I remember pushing an Omni for about 100 yards to a station once while my dad sat in the drivers seat. I’d been running around in his car all day and never put any gas in it. We didn’t make it to the station. Boy was he pissed. Lol. I see the terminal beside the yellow wire. Got it. Yes manual choke on carb. Thanks everyone!
