Anybody have a wiring diagram for the engine harness on these trucks. I need to figure out how to hook up the barometric pressure sensor on the lsa blow I installed, and I also have a dead temp sensor circuit i need to fix.

 

LT1Swap may help
GMupfitter will have what you need though

 

On a 2012 Escalade, the MAP sensor has:

pink/black or orange/black to ECM ground (X2, pin 53)
gray that goes to ECM power (X2, pin 43)
light green goes to ECM signal (X2, pin 58)

I highly recommend paying $20 to AC/Delco GM Service Information for all of the schematics for your vehicle.

 

Where does one go to give these people money for the magical wiring maps that i need?

 

Looks like it is 22 bucks to get 3 days of GM Service Information from: acdelcotds.com The site is a bit odd to navigate... PM if you need help.

 

Will the 3 day subscription allow download and/or PRINTING of wiring schematics ?

 

Most likely. You could always just ctrl+print screen and paste and print
