You are posting in the speedometer/psom thread.
I think you need to start a new thread with no start in the title.
As far as I know only a Ford dealer can change the mileage in the PSOM's flash memory.
Nobody has ever posted that worked at a Ford dealer as how they do it.
I have never seen any device at a Ford dealer auction that would do this either. Maybe they have to send the item back to Ford when they go out of business.
Did you just change out the head or the whole cluster with the printed circuit?
If you changed out the whole cluster what year was it out of?

I just replaced my psom and 2 out of 3 thumbs up. The speedometer works great now. I upgeaded and got a cluster with a tach which is great because I use it driving. All the time. So I'm stoked about those two things. The only problem is that my odometer isn't working still any ideas of what the problem. Might be I'll be working on my truck again tomorrow.

response to Mika's question
Hey Mika this might be a stupid question but I had the same problem. Have you hooked the wire cluster back up that connects to your gas tank toggle (front/rear). If not that's why as soon as I hooked it back up my truck had to pump gas for a few seconds but then fired right up.
