2nd Gen Non-Engine/Transmission Tach signal wires into the cluster

[JoshPeters]

Can anyone tell me what color the wire is for the tach signal wire to the instrument cluster is? I'm trying to install a unit that idles the truck after "shut down" for a few min to save the turbo. I have the rest hooked up, but it won't work properly unless it has a tach input.

Thanx

Josh

On my '95 it was gray with a light blue tracer, yours is probably the same. I had to use the wire for a remote starter so it wouldn't try to start an already running engine.

Thanx Illflem, That saves me a trip to the dealer to dig through their wiring diagrams!

Oo.
