Instrument cluster swap - will this work?

[TheInsanity1234]

Hello folks. First time poster in the Kia subforum.

So I've recently bought a '60 Kia Picanto 1 with the 1.0.

Obviously, the boggo spec one doesn't come with a rev counter in the instrument cluster, just a speedo and a fk off massive fuel gauge.

Now I like to have a rev counter, so I was wondering how easy it would be to take an instrument cluster from a higher spec car and swap it with the one in mine? The instrument clusters are definitely swappable. in terms of being able to fit them in physically, and the plug sockets on the back of the clusters seem to be the same regardless of what dials are actually in the cluster. The part numbers seem to be the same from what I've seen of pictures.

Will it just be as simple as plug and play, or will there have to be bodging to make the rev counter work?

Thanks in advance!
