Explorer/Mustang EFI Harness connectors... where to get? Does anyone sell a kit?

I am looking to re-work a Mustang harness for my 76 EFI build, and have a few connectors that are broken (MAF, TFI, Injector, ect...).
I would like to replace all of the connectors with new ones that would be less brittle from years under the hood.
If the wires are all good, and you have the ability to work the harness and solder/splice in new connectors, I would think it would have to be cheaper than buying a whole new harness.
Does anyone sell a kit that would have all of the connectors you would need to rework an old harness.... or even build your own? The connectors have to be available, since there are many companies that offer the new harnesses.
I think it would have a market if someone would put together the connectors all in one place...

You can search on EBay, there are several terminals sold separately, the injector terminals are sold as sets. I've never seen a complete kit. I go to the you pick yards and grab a bunch when I can. The same terminals are used on most Ford vehicles in the same era.

Buying new would get expensive quick, most are sold with generic colored pigtails attached and run anywhere from $5-$20 each. Fortunately, you don't need the pigtails or to even splice / solder replacement connectors in. You can use a pick to remove the broken plastic connector bodies and transfer the replacements over without any cutting.

If you know what to look for you can upgrade to better designed connectors using the same method. For example instead of using the same design injector connector that is going to break next time you remove it, there is a connector for the cruise control switch in most Fords that works better. Instead of using the Mustang style TPS plug (which often breaks), you can change the connector bodies on both ends to the same design as a 96 Explorer TPS. Just use a blue or black O2 sensor plug, or alternator harness plug from a 96-97 Explorer.

The TFI plug is the same as a lot of the wiper motors, which didn't get nearly as hot and brittle.

You'll find a ton of the same connectors in various vehicles in the junkyards, it doesn't have to come from a Mustang. They aren't new, but plentiful enough that you can cherry pick the good ones.
