Neutral safety switch wiring??

I'll post this here, even though it could be considered an electrical issue.
My son Aaron was given a wiring harness for his '74 Duster to replace fried, frayed, or missing wires. Unfortunately, the replacement harness has one problem we need help with.

The segment of the harness that goes to the transmission neutral safety switch has the plug on the end cut off and missing. I retrieved the terminal from the Dodge van we pulled his engine and 727 transmission out of, but its wires are different colors than the Duster harness. Can someone tell us the correct wire color orientation on the terminals of a plug for this '74 Duster?

Thanks,
Jerry
