Fuel injector system

Just completed the work on my fuel injectors and harness.
Had all 12 injectors cleaned, repaired and tested.
Rebuilt the complete injector harness from the existing 8 pin connector ( reused the connector).
Re-set the throttle linkage and adjusted the AAV.
I used the Bosch EV-1 injector connectors (required a slight modification to the injector hold down plate).
I used the 3/8" woven pre-formed split wiring harness sleeve to protect the 16 gauge wire loom.
Engine is much smoother.

Curious, who makes the injectors for the V12? Are they Bosch?
