Gray/Black at coil on pass side of engine

Also located as gray/blue at large plug through firewall on drivers side at highest point of firewall, also gray/blue at cluster.

Diesel tach wire is gray/black, located at the PCM on the passenger side firewall or in the main harness that runs along the firewall.

I'm having the same problem finding the tach wire. Do you have any schematic that shows how the gray/black and gray/blue wires relate?

On the pass. side underhood firewall, theres a LARGE harness coming up from the BCM, and heads towards the wipers (best description I can give) . In that harness you will find a blk/grey. TACH, 8 cyl. reading.
