All I know is if ya put an ohm meter from pin to pin for the two pins
for the injector drivers it's 0 ohms.

As I've been told the 165 is the same way
The 749 has two final drivers.
In the 808 (165) shop manual, they show the injectors being tied together
prior to the ecm (wiring at 332 incoming).

Curious ain't it
Cheers
