I have swapped my 12v into my 2000 dodge 3500. It's running great and the only issues i've ran into are inside the cab. I bought a wiring harness out of a 98 12v and am yet to swap it in, but im wondering where I can find a gauge cluster for it. I've been scouring the web for a 98 12v cummins instrument cluster and can't seem to find one. I was wondering if one out of a 24v would work? or does it need to be exclusively a 12v instrument cluster?
