Hey I have the white engine speed signal wire from the new pcm, but can't figure out where the instrument panel tachometer signal wire is. Does anyone know where to find it?
Thanks,
Danny

Most of the wires from the dash come out of the firewall on the drivers side, below the brake booster & to the right a bit. Not 100%, but I think the speedo wire coming from there is also white, but you need to verify this via a GM Service Manual for your exact same year truck. It will tell you "which" white also, and where it is, in the bundle.
