The Ford connector for the big power pins has part number 3M5T-14A464-NBC.
There's a guy on ebay US that sells the equivalent Volvo cables and connectors. But each way I'm looking at least about $50 US with shipping. So I've started trawling Facebook Marketplace and Gumtree for people doing home wrecks to see if the connectors can be cut. Wreckers never keep that stuff unless you happen to call them on the days they are doing the actual dismantling.
The little 3 pin connectors can be found on Aliexpress as 'Ford EPS Connector' for a few bucks each. We'll see if that works soon.
