My guess is you have to give them your mileage when you buy it and they program it in. What I don't understand is if the mileage is stored on the pcm then how come it has to be programmed into the new gauge?

I wouldn't worry about it, they are going to go by the mileage on your cluster. Unless there is some obvious signs of abuse, or your a real ****** and give them a reason. no one is going to look at the mileage in the pcm.
One does not affect the other, I have already replaced PCMs under warranty and forgot to program the mileage into the new PCM.
The new PCM just starts at 0 miles and clocks up every mile from then on.
So if the truck had 50k on it when I replaced the PCM.
The odometer and PCM will always read 50k difference.
So at 100k the odometer will read 100k, the PCM 50K.
The important thing is the odometer, it's mileage cannot be changed at the dealer level, the PCM can.
Hope that makes sense

This ^^^^^^^^ is exactly how I believe the mileage works . At least as far as the PCM & Cluster goes .
Question for you Yoda .
Can the dealer see the mileage on your PCM wirelessly ?
Once I was in for a recall for the airbags , I pulled into the maintenance bay at my local dealer , I went inside to give them my vin & mileage the service writer told me he already had it via a wireless network that reaches to the maintenance bay I was in .
My point is , if he was able to connect to my truck in the bay , then I assume he got my mileage from the PCM & not the cluster .
Was he just messing with me or is this possible?
Thanks for a response Sir .

RLK - I haven't seen the service writers connect to the trucks wirelessly without first plugging a device into the OBD port.
Not unless someone plugged a Wi-tech pod into your OBD2 connector and turned the key on.
Where he pulled the mileage from I'm not sure.
