Oil Temp Gauge

[nitrofan1]

I'm in the process of adding water temp and oil temp gauges. I am going to keep the factory units working but am adding extra ones to the A pillar. The water temp gauge I have figured out on how to run it but the oil temp has me stumped. It will be electrical so I'm wondering if anyone had added an oil sending unit on a 4.0L and where to add it? Unless there is a way to add a jumper wire to the current one which reads oil pressure (I think) hell, Ford's gauges aren't the most informative.

oil temp is a switch not a sensor

I appreciate the reply and I know it's a switch not a sensor. Where did you get that from anyway? Oh I see. I typed "sender" not sensor. The aftermarket calls it both. I have heard it both ways for 25 years when mechanics and DIYers call for them. I will get calls for oil pressure switch and oil sending unit. Works both ways.

I personally dont see any use for oil temp guage you cannot control oil temp can you? oil level guage and oil pressure would be useful tho. and yea the difference between a sender/sensor and a switch the sensor is a pot or variable resistor and a switch is on/off or snap disk.
