just wondering if a PCM from a 2001 work in a 2003 both trucks are 7700's 5.4 4x4 supercabs. The donor truck (2001) I have has the instrument cluster/PATS transceiver/proper PATS key/ and PCM.

Just wondering if I swap out all items if I can get the speedometer to work. I have the pin outs for the 2001 F150 5.4 does anyone have the PCM pinouts for the 2003 F150 from a workshop manual

PM me if you do please, sure would appreciate it

reason why I had asked is the instrument cluster works other than the speedo. I di a gauge sweep and all gauges sweep but I still have the 500 and 1502 codes. VSS signal loss. I am going to switch out the PCM, PATS, Instrument cluster from my 2001 7700 parts truck to elimate if its the speedometer or not. Will let interested viewers know how it works.

will do over the weekend hopefully, - 31C with -41 with a breeze, tools are very cold and the plastic very brittle

well both instrument clusters, PATS,PCM's and ignitions are out have pictures coming. Tick me off we have our company Christmas Party and want to stay working on the truck

1)2001 and 2003 PATS plugs are different. Wire colors are the same,...Orange,Blue,White,Black

will update later,....brrrrrrrrrrrrrr it is cold out, my eyes are frozen open :laugh (no heat in the garage)

Well well well, got the PCM, PATS and the instrument cluster in. Hooked up the battery, put the key in the ignition wait and watch the theft light,.... all ok turn it over and away it started. SOOOOOOOOOOO, the 2001 PCM will work in the 2003 so far. Put the truck in gear and the truck now has an operational speedo,.... woohooo!!!!!

no as for everything else, who knows The truck in the back is up on jack stands so the 4X4 I have not checked. No check engine light.

I was wondering about the Keyless entry code and checked that out and it too works. I didn't know for sure cause it has the RAPS module that is controlled by the PCM but the code still works.

back at it tomorrow to finish the swap and re-install all the trim.

everything works, 4x4 and all. I am in the process now of switching all the lock cylinders over from the wrecked 2001. Sure nice not to worry about locking the keys out or in the truck without a door key. I do have the keyless entry but the battery is dissconnected while I a working on it

-1 out today and can stay longer in the garage with no heat. Sure nice to have the parts truck sitting right beside you as you work on the truck.
