which wire in the little connector going into the gauge cluster is the one for the tachometer? i've heard white, and i've heard grey, so which is it? or is it either...you guys that have tachs let me know what you did. i want the stock tach to not work and the new one to be the primary since it will be more accurate.

 

Wait till i get back down and you can copy my setup. Mine is on a white wire

 

yeah...but i don't want to run it from that wire...i want to run it from the wire on the harness plugging into the cluster. maybe it's the same wire.

 

is there anywhere on the web with a wiring diagrham for our trucks????

 

Matt, like I said in the other thread, the white wire on the #10 pin on the PCM is the tach output wire. It is the same wire on the cluster. There should only be one SOLID white wire up there.

 

so i can just clip the wire going into the cluster and hook it to the one on the tach and i'm in business?

 

it may be different now but on my 99 i had to hook up one tach or the other.
