Can any one point me in the right direction for a pin out on a 2000 f250 with the 5.4l Triton ? I've gone through several that don't end up correlating to the proper pin locations, color and im trying to locate rpm input

thanks all

Not sure if this one applies

The linked Expedition data is close but is not quite the same as the Super Duty.

There is no "RPM input" signal to the PCM although there are signals, both input and output, that will allow the derivation of RPM data.

What are you trying to accomplish?

 

So I put a 24v in a 2000 with a 5.4. all good and now trying to get my ac and tach working in the truck. AC lines done and charged and I can jump compressor. trying to feed the PCM tach signal from a tach box to enable it to let the compressor run through the ford wires and then trying to feed my tach gauge signal from the trans controller that derives rpms. I was able to get my speedo working via trans controller that corrects for gears and tires, but the diagram I have was incorrect for tach output as that pin was empty. so thats why im trying to find the super duty pcm pin out for a 5.4. ive been looking online for about a week just figured someone here may have it
