What a good idea... 'read the FSM' which is a gentle way of saying RTFM

So to share my enlightenment, the plug I show from my ZR is correct...there are two blank [E & D] pin sites. Pin F is for TCC system which is the Torque Converter Clutch and since this connector is also used in the L98 guess they standardized since you can get an automatic in L98 variant. Pin C is for the Selective Ride Control.

I also found the test required if you throw a trouble code 33... but FSM also states this can be tripped "if you experience rough or unstable idle.." which I certainly did when I fired up the engine after the fuel injector switch out... it settle down and now runs like a kitten but I think ECM has the code in memory so I will clear.
