Looking for 70 dart swinger rally harness

I suppose I should fill in a gap but please remember I didn't dig this hole, Ma mopar did...
If you have one of the pre 70 A-body jarnesses that doesn't have the round main connector but has 2 of the flat inline type. You'll need to do a lot more moving wires around after you trade a flat one for a round one,
And if you plan to do this yourself , pay close attention to the wire locations relation to the key in the connectors. That key is at 12 oclock in the physical part but is drawn at 9 oclock in the factory schematics. Where the key is hown rotated 90 degrees the wire positions are also rotated 90 degrees. Engineer drawings arent as simple to follow as something that Fords EVT manuals.
