'70 Dart 392 Project; what direction?

Well that would've been the smarter decision! haha Live and learn...

So I'm going through my megasquirt stuff and holley "gen 3 hemi connector kit" and holy crap the holley kit is garbage. They have 21 connectors in the kit with not a single applicable label. I emailed holley and they said they don't have a part number reference for what each connector is for. In comparing some of my basic sensors; cam, crank, injectors, coil packs... not a single connector fits. So far looking like a waste of money.

So I'm going through a connector list and will be buying individual connectors I'm guessing.

Here's a list so far of sensors that I have and their connectors that I'll need:

EV6 injector connectors X8
crank sensor (factory hemi 3 pin connector)
cam sensor (factory hemi 3 pin connector)
Coolant Temp sensor (factory 2 pin connector)
Ignition Coil Connectors X8
Bosch Knock sensor connector X2
LS Idle Air control Connector X1
LS TPS Sensor connector X1
bought these sensors for a GM LS cable throttle body: JEGS 14531: Idle Air Control Motor and Throttle Position Sensor for GM LS - JEGS
O2 sensors (came with connectors)

What I don't have is an IAT sensor yet as I don't have an air intake setup yet. Recommendations?

I swear the research/prep work on this stuff is the hardest part!

If you are using a megasquirt, all you need factory connectors for are the cam/crank sensors, and the coils. Everything else is fairly universal/GM style. I cut up a factory harness and made my own reusing whatever I could, but ran new circuits for TPS, IAC, IAT, MAP, and Coolant. I used an analog sensor for MAP because I didn't want to run a vacuum line inside the car for the on board map. Instead, I use that one as a barometer sensor. I also added analog sensors for oil and fuel psi. I'm not using knock sensors.
