Automotive power steering unit connector identification
Automotive connectors may very well be proprietary designs done by the company itself or on special sourcing contract with a connector manufacturer. As such it is common that you will not be able to independently source the connectors yourself. 

A secondary concern is that these cables also use special crimp on contacts that require very expensive tooling to reliably apply the contacts.

It is an unfortunate byproduct of the mass production world where it is next to impossible to get individual replacement parts and instead have to purchase whole subassemblies instead. Have you considered visiting a auto salvage yard to see if you can get a used cable assembly?
