New Underdash Wire Harness Question

I guess you understand there is a main underdash harnesss, and an add on accessory harness(s) for the option(s). If you have an A01 option you should also have two prong door switches.

The accessory harness parallels and plugs into the main harness. I have not done 69 Dart in color PDF but if you read between the lines well, this may help with the A01 option in your Dart.
