Standalone wire harness for 2006 LS2
hello all
I am in the process of swapping in a 2006 LS2 from a manual Corvette going into a 1974. I am at the part where I am trying to take the stock wiring harness and convert it to a standalone use for my project. most of the information I am finding (LT1tech.com) is for truck versions of the platform, and or not specific enough for the harness I have. I am wondering if anyone here has the mapping/ pinouts for this engine and/ or has done a similar swap and knows where the skeletons lay. the issue I am having is the pinouts I am finding are close but not exact and I don't what to pull the wrong thing. additionally there is the sub harness that runs thru it that has 2 twisted pairs (1- yellow/grey, 1- yellow/black w/stripe) that run to what I think is the MAF/IAT terminal along with the 4 wires going back to the black Connector for the ECU. any help you can provide would be appreciated.

You can get the OE wiring diagrams from Alldata DIY...you can get a 1 month, 1 or 3 year subscription..."twisted pairs" are normally found on the wheel speed sensors and CAN bus...a 1 month subscription is $19.99.
