Those are UGLY though. They aren't built to the exactly like the OE one and are slightly off in color as well. 5 gauges isn't a big deal since the OE had 5 gauges. It's jsut teh 5th one is either a Clock or a 4WD indicator.
I'll probably replace all of the gauges eventually. Probably end up keeping the YJ dash. All that I'd need to do is make a mounting bracket for the small gauges. BUT I'll probably wait to do that. It's nor a priority as those gauges aren't crucial as long as I know they're working or not. Actually, I forgot but I can check the voltage at the battery with my 2M radio. It does a power check when it starts up so I have second gauge.
i assume you have a clock on your radio as well, so i would say forget about that one. I would go with an AFR gauge instead the 4wd one (i mean really that is only a light, you don't need a gauge for that and is not even displaying when you're in Low anyway).
i don't have the P/Ns for the ones i used but they are autometer pro-comp and I ended up with 7
Fuel Pressure - mechanical
vacuum/boost - mechanical
Oil Pressure - mechanical
Water temp - electrical, i used the stock sender off the Jeep and seems to display correctly
Fuel Level - electrical, same here off the stock sender (there are 2 types though, need the one that matches the the Jeep sender)
Voltmeter
AFR - led based on narrowband output
the empty space to the right of the AFR gauge i am planning to get a switch panel for lockers front/rear, air compressor, e-fan, winch (although i think is too far away), offroad lights and not sure what else (still trying to figure it out)
