Ive started my wiring saga.  Ive got the 6 stock injectors plugs ready to wire to the EK6 Harness.   
  
The loom digram for the injectos has 7 wires   
-DIG OUT1 
-DIG OUT2 
-13.8VDC INJ 
  
-INJ1 
-INJ2 
-INJ3 
-ING4 
  
Im going to be doing batch firing on my JZ, 3 injectors output firing 2 injectors each.  
  
Each injector pair has 2 black wires and a common white.  Do INJ1-4 provide a ground and I should run the negatives of the pairs to them and wire all the whites to the larger 13.8vdc wire?   
  
Not a total idiot, but Im having a difficult time on this one. 
  
This help point me towards the wiring order, maybe help someone answer my problem? 
  
The E6K can only provide 4 fuel outputs, therefore it cannot control each cylinder’s injection 
on an engine with more than 4 cylinders. For 6 or 8 cylinder engines, the E6K can operate in a 
semi-sequential mode. With the Ign / By set to 2, each injection will occur once per engine 
cycle. The injectors need to be paired to cylinders adjacent in the firing order. For example, 
on a six cylinder engine with firing order 1-5-3-6-2-4, the injectors would be paired to fuel 
channels as follows : 
Channel 1 INJ1/INJ2 cyl 1 and cyl 5 
Channel 2 INJ3/INJ4 cyl 3 and cyl 6 
Channel 5 Digital Out 2 cyl 2 and cyl 4
