Looking for 1974 Plymouth Duster wiring diagram

'74 is a disaster is what it is.

1 year only seat belt ignition lock out, and that stupid "delay box" or whatever that's a separate circuit board. I'm not saying they aren't out there, but I have yet to see a wiring diagram fully depict all the stuff that was in the '74 harness. It's basically a 1 year only deal.
