89 YJ gauge cluster question

I recently bought an 89 YJ project.
4.2L I6
I’ve stripped it down to restore the dash and the gauges and found that the gauges are individually wired and not part of a cluster. Has anyone seen this ?
Any advantage/ disadvantage to switching to cluster vs individual replacements?
I’m pretty sure I will need a knew wiring harness as well.

The printed circuit boards are prone to bad connections. Most of us cannot trust the accuracy of one or more gauges in our rigs due to that. The connections can often be cleaned, but it comes back too. So some guys will attempt to run wires to each gauge, and others will just replace the gauges with something A/M. Yours looks like the gauges have been changed out and hard wired but you didn't show the gauge face side so I'm not sure. Kind of a hack job the way it has been cut up, but the main question is, does it work? Knowing what I know about the circuit boards I probably would not try to replace it with something original, especially with the base harness apparently missing. There is a multiconductor plug that seems to have been removed. Also you probably don't know if the senders are original either.

If you want to replace those with their current equivalents, the sunpro brand was bought by bosch and they currently sell those same gauges. Fixing/changing out the gauge cluster was the first thing I did when i got the jeep, because my original gauges half worked (lots of circuit board problems as others have mentioned). If you do replace them, do not use the mechanical version of the temp gauge as it seems to have poor quality control and the units fail quickly.

Instead of hacking up the old gauge cluster housing, I bought a piece of sheet acrylic and epoxied it to the back of the the middle dash face; after cutting out the holes for the gauges, it gave a nice backing to mount them from. I installed the gauges individually from the front and it turned out fairly clean. It's been seven years since this photo and they look as good as new.

Did you have to do anything to the fuel gauge sender to make it work with those gauges? Any other senders need to change?

It looks great. Like it belongs there.

Why give up?
I took me four years to get my restore/refurbish/4.0 install done on my 89 a little here, a little there, a big push at the end and I’ve been reaping the rewards for 6? years now. Staying power to the point of completion is a form of delayed gratification and is a neurologically healthy thing to do.
