I think it is a typo because on the c3 pinout it shows circuit 603 dark green wire on pin 30. Why does c4 only go to 24 pins though I wonder when there is 32?

https://www.ak49bwl.com/other/wires/1997K1500/ .. That should have everything you'll ever find in a stock 97. The PCM diagrams are EnginePerformance-......I don't know why it cuts off the file names but 50 is for 5.0 and 5.7 engines, 43 is the 4.3, 74 is the 7.4...

why does the connector c4 on showing 24 pins when there is 32 on my connector? Could it be my truck is a 2wd an not 4wd?

ok I'm an idiot. I figured the c4 plug out. Getting frustrated I cannot get the relay to provide power to the compressor with all the pressure switches jumpered to ground.
