the 1227727 has 4 connectors with 22 pins each and is weatherproofed
the 1227730 has 3 connectors, 2 with 32 pins, one with 24 pins, non weatherproofed
internally, they're basically identical, so you can run a program from one on the other easily, you would just have to change the connectors on the harness.
the 7730 was used in a LOT of applications, the 7727 was only used on W-bodies and corvettes.
It would be mucho easyer to find a replacement 7730 than to re wire your harness to use a 7727, unless you require a weatherproof ecm.
