I'm Awesome
Hey all, I'm finishing up a engine swap on my 1989 C1500. Was originally a 4.3 auto, now 6.0 4l80. Everything works but I can't seem to get the speedometer to work and it did function before the swap. Tried splicing the original vss Purple and yellow wires to the vss output of the trans with no luck. Then I tried wiring the 2000 ppm vss from the LS harness to 16A in the cluster, nothing. I've searched through manuals, schematics etc. What am I doing wrong?
