Hey Frankie!
I see the wiring kit you bought is complete, engine, interior and rear. It looks nice, I like that it has modern fuses.
Because you’ll be using the Dakota system, you won’t be using the under hood wiring for the oil and temp gauges. The Dakota wiring for those sensors will need to go through a hole you’ll make in the firewall. Volts, tach, turn signals, high beam, brake, fuel and tach signals can be picked up in the dash. Dakota Digital has optional modules to acquire transmission selector and speedo signals, you’ll need to run the wiring to the transmission.
The AAW kit looks nice but a lot of plugs are loose, un-terminated. As you’ll have a lot of crimping to do, I suggest you get the crimping tool for the Packard plugs as they’d recommend. I’m a fan of also soldering after crimping.
As you have a 1972 car, did this kit include the seat belt warning light wiring?
Don’t forget a few spare extra wires from the dash to the trunk!
