So I picked up an 03 ram 3500 4x4 duelly 6speed nv5600 4 door. The digital read outs on the bottom don't light up. I picked up an instrument cluster from an 03 3500 4x4 auto. 4 door. I didn't realize it at the time . When I got home And removed mine and went to install the new one I then realized the white and Grey plugs are on the opposite sides. WHY and is there anyway to switch them or remove the digital displays and if i install them in mine will they work ? PLEASE HELP AS I NEED THEM TO WORK TO PASS AN OUT OF PROVINCE INSPECTION.

First need to id what 03 version you have pcm and ecm or just ECM.
readouts are Not digital, Vacuum fluorecent tubes.
Cant just swap EMIC (cluster) , to avoid theft/fraud, VIN mileage/hours and or security info have to match, need some one able to flash ROM memory on EMIC.
probally gonna cheaper to fix yours or find proper rebuilt cluster.
I would try Google cluster shop by you

thanks for the laugh 🤣🤣
Most shops near me are Cluster shops...

On the seriously side, the laws around odometer have had engineers build in lots of controls. This requires a like for like and many times maintenance will not work.

But check pinout and see if you have power to the appropriate circuit. I've repaired a few ribbon tapes, PC boards with bad spots to power the circuit.

Check to make sure it is the cluster and not something in the truck. I have repaired things that didnt need replaced only later to find the root cause, on my own vehicle..

I had my mileage display go out on my OEM cluster (04.5). It was not the solder connections on the board, all were good when I opened it up. The display would fade in and out. It eventually got to the point where you just couldn't see it at all.

I picked up a used cluster from an '05. Doesn't matter if you get an auto or a manual cluster (my truck is an NV5600, cluster was from an auto). Took it to a local place that swapped all the information from my cluster to the "new" one. I think it cost me $60 or so do have them do that. Have all paperwork, completely legal to do. Fully functioning for 7 years+ still.

It’s easier to find a cluster with similar mileage. You don’t need to program jack squat on the 03-05 clusters.

Just need to find the cluster out of a similarly optioned truck. (Power locks, windows, etc.) The exception is that auto and manual clusters are interchangeable.



Post pics of the connectors on your original and the replacement. Also post p/n of both.

The only thing that needs to be "programmed" per se is transferring the mileage of your cluster to your "new" cluster.
It's unlikely you'll find a cluster that's got your exact mileage on it. It was hard enough years ago to find a cluster that was in good shape that wasn't outrageously priced, let alone one that would match the mileage of the truck. If I ever want to sell the truck (likely not) I wanted it to be spot on. The companies that swap this information do it legally. Being that I couldn't see the mileage either, I didn't know exactly what it was since I had driven it some time without being to see the display. They were able to pull that info from the cluster accurately.

It's been so many years ago I did this, I can't remember if I swapped the fob receiver from my old cluster to the new one as well to avoid re-programming any of the locks or not. I know for a fact I have the receiver from 1 of the 2 clusters in my box of parts in case I ever needed it for something.
