Good morning. Did a ton of reading on the glow plug system yesterday and did the OHM check last night. The wire colors on the diagrams I saw posted didn't match the wire colors on my truck. I disconnected the 4 pin plug right behing the alternator and got infinity on the red wire leading to the right bank glow plug harness. I have code P0637 and I want to correlate the red wire to the #3 glow plug circuit. Can anyone confirm that I'm on the right cylinder? Thanks for the help. All other pins on that plug read around 2.3 Ohms so i think I'm pretty close.
