Can anyone help me identify a few things on my 2006 5.3L?
#1 - Sensor on front of intake, right behind the TB:
#2 - The hose that runs from the sensor in #1 runs to the back of the engine on the drivers side and was disconnected from something. What is the hose suppose to plug in to? (end of hose is #1)
#3 - The vent hose on the transmission splits and runs toward the engine and ends with a check valve. the other end was loose. Any idea where that end with the "?" goes?
#4 - This sensor above the starter:
#5 - This module, looks as though it was on the inside of the cab:
#6 - This gizmo was tied around the negative battery cable near the battery terminal end, and ran straight to the PCM:
Thanks in advance for any help ID'ing this stuff!!!!
