I can't help with the swap but I'm hoping you give us updates!

What are you starting with? Do you have the original 4.3 harness? Has pcm been had vats and such tuned out? Some good info at https://lt1swap.com/wiringharness.htm like diagrams and much more. Also universalpatcher is good for playing around with that pcm with a cheap laptop cable.

Cool project! I had a '73 Vega wagon about 30 years ago. I miss that thing.
