I need help identifying some plugs on an LM7 harness (2003 Chevy Tahoe 4WD). In the first picture, there are two unidentified plugs: one at bottom center near the MAF plug and one towards the upper left.
In the second picture, the one near the rear O2 sensor (black tape). Is that the VSS that connects to the transfer case? If so, what is the plug just left of and on the same run as the transmission plug?
Any help would be greatly appreciated.
Thanks
Ted
