DO NOT PLUG IT IN TO YOUR TRUCK!
this is how to do a cluster swap correctly. it isn't just plug and play, the mileage and vin are stored in the cluster, if you just put it in it will throw flags with the computer.
you need a cluster from your year truck (you will need to verify further but i've read that cluster interchangeability is along 02-03 for older 3rd gens and 04-05 for newer 3rd gens) if your truck has power locks, the replacement cluster also needs to have come from a power lock truck. with power locks, you will reuse your rke module on the back of the cluster.
the replacement cluster will need to be sent to chrysler to have your vin and mileage programed into it (you will estimete how many miles you will have in two weeks, as long as you're close you will be ok).
as far as sending it in to chrysler, not a lot of dealers will know how to do this. the parts manager at avondale dodge in arizona knows how. you send it to him, he sends it to chrysler and it gets sent back to you. all this gets done for around $100.
i've done this procedure on two trucks- yes, that is a srt-10 cluster on a 4.7l sxt level truck
