Wish I could help you out on this one but since mine is a Gen 2 and 7 years old now, the temp sensor connection was different.
Plus I had it installed by SVT Tech at the dealer. I know he had to tap into one of the PCM plugs.
Like you said the .pdf install file leaves a lot to be desired.
DUDE!!! Thanks!!!
Okays this is what I figured out...
The Throttle harness is straight forward, one end goes to TB sensor, other TB motor, and the last connector to the original TB connector in engine bay..
The 2 way extension (which is not mention in docs), is for the BEVIS connector which is relocated from the original mount point on manifold to its new location on the SC.
Finally... This is where your hint of tapping into the PCM...
No where in the new documentation mentions anything about tapping into the PCM.
However, I was able to search and locate the original 2011 SC installation manual(pdf). In this pdf, it describes where you need to tap into the PCM for the intake temp sensor (pins 36 and 56). At least now I have a fall back..
The 2019 version, the documentation only states that one end of harness connects to the intake temp sensor, but no mention of the other ends.
The ****** thing is... I now have to destroy a nice wiring harness, let alone, the wires are different colors from the 2011 doc so I can now connect to the intake temp sensor... I think I need to have whipple provide the older temp sensor harness with the PCM pin connected to it as stated in the 2011 version.
Looks like I can still proceed on turkey day weekend
Hopefully, Whipple can validate my guess work..
Much Thanks MTF!!!
