What Harness and any tips??

I'm in the process of rewiring my 74 Duster. I have 4-5 factory harnesses at my disposal for various connectors and such. Could have probably made a good one out of it but I went with a Painless 21 circuit kit. I just don't trust almost 50 year old wiring.

I relocated the MSD, fuse panel, voltage regulator and starter relay to a panel under the dash where the heater box used to live. I'm also replacing all the light sockets and switches in the car with new ones. I've added an electric fan, Hella H4 conversion with relay harness for the headlights. I'm also running provisions for a future electric fuel pump and nitrous. I'm not the most savvy when it comes to electrical so I just take my time and do one circuit at a time.
