Message The Wiring Specialties EFI harness appears to be wired so that the injector common wire is switched 12V instead of constant 12V.

On the WS harness, the common injector voltage is pin 45 on the ECU connector, not pin 58 like the factory harness.

So...if you are checking your injectors through the harness, (FSM - Diagnostic Procedure 36 or here ...La-Z-Link) you need to select pin 45 instead of pin 58.

I hope this helps someone (to do this check in ten minutes like it is supposed to be done instead of wasting half your afternoon)
