Ignition wiring questions

Hey all,

Working on my 1972 Plymouth Duster 318 project car. I needed a new column and have gone with a keyless column. I am going to use a Peerless universal ignition switch and mount it in the dash. I am also installing a remote mount kill switch inline on the start wire.

My question is if anyone can off hand tell me what each color runs on the stock wiring. I know I can eliminate the two small red, cause they are the key buzzer. I don’t know what the orange wire powers. I hope to eliminate anything other than power, ignition, acc, and start. I will post a couple pics for reference. Thanks in advance!
