Painless makes a harness, otherwise buy a junk car and pull the harness from it.

It will depend if your Mustang was Mass Air or Speed Density. There are all kinds of harnesses ou there for MA, SD, not so much.
Mass Air will have a sensor on the air intake close to the filter, Speed density will not.
They run different computers. Mass Air set ups react much better to changes.
The guys on the Small Block Forum could tell you more than you ever wanted to know about this swap!
