I got mine from a grey wire I think somewhere in the dash. Its been so long now I cant remember where it was. If you dont find one pm me and I'll track down the wire for you.

Actually after thinking about it a second it seems like theres a wire taped up from the factory just for that somewhere around the drivers side kick panel. It was grey I believe.

Found this in my notes from doing my alarm.

On diesel vehicles the tach wire is green or white,
in a 42 pin plug under the clamp on the engine side of the air intake duct.

Still looking thru my notes right now to see if I have more info.

Another note Ive got shows :

The DIESEL TACH wire is a WHITE/PINK running beside the brake pedal.
