I have not yet installed mine as I need to have the mileage, and hours set.
I was at a local dealership the other day and just for kicks inquired about having them send out the cluster and leaving my truck there so the process could be documented for DMV and warranty reasons. The SM said he would look into and get back to me.
I just a voicemail from them stating they cannot do it, and strongly recommend I do not as it will absolutely void all warrantees. I am not sure I really believe that but if push comes to shove its us against Fiat, and Fiat can afford to push and shove much harder than we can.
Still mulling the idea over I know a lot of you guys will make arguments, that the PCM, BCM, ECM or whatever stores the actual mileage and there is no way they can deny me warranty etc, and that all sound good but again Fiat holds all the cards pretty much here. But I want this cluster, what a conundrum, I going to keep looking for a dealer who can at least document the process for me.
