I'm swapping the idiot lights cluster for a gauge cluster. 91-96 xj I have a 91. I have located the 2 senders which I believe are these two:

Oil pressure




Air temp sender





Went to autozone and this is the sender I bought but I think it's the wrong part.




After doing a bit of research I think what it's supposed to look like is this right here




There's so many parts that say they are the right sender but look different. Can somebody please clarify.

One by oil filters correct. Coolant should be in area of green circle. As for there look as long as its for a gauge your good to go.

I located the temp sensor here but this one only has 1 wire to it as you can see in the picture below. In all the write ups I've seen the sensor that guys have used to replace the light one has multiple wires and appears to be the same sensor used for the cpu that is in front of the engine. Not the case here. This is the temp sensor I have right now with my dummy gauge.



I went to autozone and originally got a sensor that looked exactly the same as the one I have right now. The guy told me it was for a gauge cluster however does that seem right? Do the light and gauge temp sensors both look the same?

I'm starting to lose my mind here trying to find the right damn sensor for this project.

On the write ups I have seen this appears to be the sensor I should be using:



BUT this can't be right as the threads on this sensor are way too big and this does not connect to the single wire I have by my valve cover.

Thats a coolant temp sensor your holding goes on thermostat housing . The temp sender/switch is the single wire one on rear of cyl head. Even though both old and new look same the difference is one lights a light the other moves a gauge.


Do the light and gauge temp sensors both look the same?

YES...

These are the ones I used

My temp sensor looks nothing like that. Did they change after 91 or something? My fuel pressure sensor also doesn't connect to a pigtail like that it hooks to a male connector as seen in one of my first pictures

Also thanks for the replies guys

I think the dummy lights take the "plug" type where the full gauges take the "post & boot" type you should just be able to replace the connector.

So I not only need new senders but new connectors as well?

I've found this it says it for a 91 with temp guage

Just replace the sensor no plugs/connectors are needed. Wire should just stab down onto top. Yours is not connected in your pick the other one is. Jeep sensors change thru the years ....
