Guess I didn't address the connector. You could probably do more research and find what the actual connector pn is. Heard of people using the 8hp in classic cars, meaning some sort of retrofit with the harness. Hell, I would try to design and 3d print one first before taking in. But have a look here, maybe not the specific one you need but I bet you could find the proper connector with enough looking into it. These are just some of the first ones I saw although you would have to carefully repin the new connector. Also saw whole valve body/tcu assemblies for as low as 120 euro on de eBay.
