The PCM is the computer that's in the engine bay in the passenger side of the fire wall with a big harness of wires going to it. The wire is in that. This is where I spliced into it. But that wire has to go back into the cab to plug into the dash cluster since some trucks have a factory tach. So I'd look for that color wire in the plug in gauge cluster(wish I did it that way). I'm pretty sure it's there
