Last Summer some of our D-Jet owners discussed this topic here:
1973 450SL Engine Harness Parts Needed
The consensus of that thread leans toward purchase of a new engine harness. I appreciate that for our members who are interested in OEM integrity.
My harness was in need of some work - dried out, brittle, cracked, connectors. Google led me here:

Some VW D-Jet guys have built harnesses using double cantilever terminals. AMP/Tyco has made these for Bosch / Lucas since they discontinued the male spade to female rolled clip terminal in our harnesses. If you buy Bosch part 1287013003, you are buying an L-Jet connector with these terminals.
VW 411/412 enthusiast Ray Greenwood has found a way to adapt these 2 pole connectors to fit our injectors and sensors. Simply cut back the housing to its base. His expertise got me interested in building engine harnesses. Ray is of the opinion that OEM D-Jet harnesses are flawed in design at the terminals. Ray says that electrical resistance is critical at every connector except the TPS and Start Valve. I tend to agree with him because I have seen the noisy signals running through my harness on an oscilloscope. I am not all-in yet, but I have been experimenting with this since last Fall.
I harvested connectors from mid '90's Audis, Volvos, V-6 Saabs and V-6 Saturns. The Audi ones are the most versatile because they can be separated from thier housings (pink plugs in the pictures). These connectors are rectangular and fit snug in our injectors and start valve. They require a little dremel work to fit our air temp and coolant temp sensors.
