In the process of adding an overhead console with mpg to my super duty. I need to connect a wire for the "injector cycle duty", where can i find this? I pulled the pcm where it was supposed to be either pin 9 or pin 43 and there is nothing there. Thanks

 

Wild *** guess, but maybe that's for diesels?

Well the 2002 -2004 2 door console with mpg install is done in my 1999 f250 superduty 5.4 xl. This is not as complicated and expensive is it may sound. There is a guy by bird who sells these and it CAN get expensive , even 100 dollars for the wiring book for the mpg to work. I just went to wrekn yard and got a console with computer for 40 bucks and was able to cut off the harness conector that plugs into the console and made the rest of the harness . You can find all over the net how to cut the liner and wire the temp sender, but to wire the mpg computer into an xl, there is not a whole lot of info. There are 3 things required for mpg to work, speed sensor,fuel tank level sender, fuel flow. All these are at the pcm PINS, and not always in the harness. So i just unpluged pcm harness and drilled slot and added these wires into the plug harness and it is working. Here are the pin numbers for the 1999 5.4 superduty

At pcm on drivers side near fender well
pin 9 yellow/white wire = fuel tank sender
pin 58 gray/black wire = speed sensor(this is only wire that was in pcm harness)
pin43 orange/light green = data output link fuel flow
