These are the swaps where my eyes got blurry on four gray wires at 2 am in the morning:
After they were all out, putting in the last one, I realized I had made a miss-step when I saw a wire mis-labeled:
Blue C2-67 GRY TO Blue C1-46
Blue C2-66 GRY TO Blue C1-45
Blue C2-65 GRY TO Blue C1-47
Blue C2-64 GRY TO Blue C1-48

Pin Color CKT Function
64 GRA 416 MAP Sensor 5V reference Pin "C"
65 GRA 705 EGR Valve 5V Reference Pin "D"
66 GRA 474 AC Press Sensor 5V Reference Pin "B"
67 GRA 598 Fuel tank Pressure Sensor 5V Reference
2002
45 GRA 474 5 Volt Reference (A/C Refrigerant Pressure Sensor) (Factory)
46 GRA 474 5 Volt Reference (Fuel Tank Pressure Sensor) (Factory)
47 ! GRA 705 EGR Pintle Sensor 5V Reference
<<-What does the exclamation mark mean
48 GRA 416 5 Volt Reference (MAP Sensor) Pin "C"
What do the “!” mean in Pin 47?
I see this statement in the docs:
“EGR circuits will be shown for 1999/2000 conversions. The EGR wires can be installed in 2001-2002 applications if desired.”
If this is the case, since I have a 2002 PCM, can I leave this disconnected and disable the test?
Also, I have questions about
:
31. Red C1-36 DK BLU TO Red C2-38……………TEST FIRST! 99-02 PCM’S
What am I testing? Why?
Since the MAP sensor is right there, I should be able to check continuity between that pin and the connector fairly easily (assuming I'm thinking the correct way about this), right. Which might make the corresponding wire it was mistakenly swapped with identifiable.
Bit I want to make sure I get ALL of them, and not keep tugging on that harness re-fitting it multiple times.
