1991 Wrangler Stock Gauge Part Numbers/Sending Units
I consulted my Chrysler parts manual, chiltons and a few other sources and can't seem to get a defining answer.
Since my new gauges are here, I'm attempting to find sending units for them. To do that, I'll either need the part numbers of the stock gauges to properly match them up or I'll need to know the exact sending units to work with the new gauges. Of course, VDO is less than helpful at knowing exactly what I have so I'm hoping to get this information and go back to them.
Here's what I know so far. Hoping someone can fill in the gaps. I've BOLDED the stuff I'm not sure about.
The Speedometer needs a hall effect sender. VDO is saying I might be able to use their 340-013, which is a Ford Transmission sender but works with some Chrysler transmission. Does anyone know if the AX5 is a threaded-on or push on style sender? or what sending unit would work with aftermarket gauges?
The tach needs no sender as it gets it's signal from the coil or alternator.
The fuel sender appears to need to be a 0-90 Ohm. Does this sound correct?
Oil Pressure I have no idea about. Anyone have a stock oil pressure gauge part number? or know the type of sender required from the stock oil pressure fitting?
5. Temp I'm not worried about because I already have an aftermarket gauge that comes off from the themostat housing. I'll be replacing the old gauge with the new one on the same house/sensor.
6. Voltmeter should not need a sender.
This is all so confusing! Thanks for any help you guys provide. Not know what the Jeep is doing while driving is frustrating.

1. the AX5 speedo sender is electronic so it will be a push on connection.
2. the tach gets its signal from the coil.
3. the fuel sender, they make 2 different ones, 0-90ohm and i believe its 90-180ohm, so you have to get the right gauge for the sender.
4. the oil pressure sending unit is located on the passenger side of the motor near the oil filter. they are a common part, most auto part stores have them on stock.
5. the temp sensor in the thermo housing is for the computer, the one for the gauge should be in the back of the head up near the valve cover on the drivers side rear next to the firewall
