? about factory tach
? about factory tach I need to know how the factory tach gets its signal from the pcm. I have a 2002 fbody. I installed bs3 and the factory pcm is getting the crank signal. I'm seeing the rpms with autotap and my stock fans and all the rest of my gauges are working besides the tachometer. I traced the # 10 white wire coming from the red side of the pcm to the weatherpac connector ontop of the passenger fender and noticed it does not go anywhere. Hopefully I can trace down how the tach is fed and get it working again.
