I have a 2000 camaro harness with a 0411 pcm
Everything was swapped in the tune. Everything works except the speedometer. I changed the vss sensor twice.
Hptuners doesn't show speed. I swapped clusters 4 times.
I did run a jumper wires from the sensor to the pcm. I was about to tap into 20 and 21 on the RED connector but noticed the right colors and the right position is on the BLUE harness.
Should I tap the BLUE 20 and 21 which are purplet white and green/black?
Or stick with the diagram and tap the two on the RED connector? Wrong colors for 20 and 21.
Now that I know specifically what your trying to do, Try Looking up a 2001 or 2002 Chevy Express Van with L31 5.7L
It used the 411 PCM as well
If you cant find one online let me know.
yes i have the 411 pcm from 2001 chevy express van and i really could use a pin out for it to my 96 gmc 1500 with the l31 5.7 plus i have a lokar floor shifter on my 4l60e and i recently installed a stage to cam
