Okay, the transmission will be a C6. Unfortunately the pigtail that's part of the neutral start switch plugs into the main wiring harness, there isn't a separate pigtail that connects the two.
Standard Motor Products shows a repair pigtail that can be spliced into the main harness to repair that plug (P/N S743) but that's not the right plug, it's only two terminals and the NSS should have four terminals.

This is the NSS for your truck. Just so you know, it also operates your backup lights.

Before buying, be aware that the C6 uses a different NSS than the C4.

1978/79 F100/150: D8TZ-7A247-B .. C4 NSS (Motorcraft SW-1491) / Obsolete
