Where is the best place to go threw the fire wall with after market temp gauge. Not a fan of the dummy light!

 

I had multiple empty holes in my firewall, the one that I chose for my aftermarket mods is just centerline of the master cylinder, and just below it,

 

You can always swap for a full gauge cluster. You only need to change 2 senders on the engine and it should plug and play.

 

You got me thinking now. I didn’t realize it would be that easy. Any suggestions on brand and where to buy/order?

 

If you can't harvest the sensors from the same junkyard XJ as the cluster - any autoparts store, just stick to a big name brand.

 

Odometer reading?

 

Just hit 203,000

 

I mean on the donor instrument cluster.

Has anyone addressed that?

 

The mileage on the donor gauge cluster cannot be less than the original, I could not find one that was close, now my jeep legally has an extra 50,000 miles on it.

 

A quick search tells me that any vehicle that is 2010 or newer must show correct mileage, given production stopped in 2001 the XJ's no longer fall under that category.

 

I haven’t picked up a donor cluster yet, but I’m glad this was brought up I had absolutely no clue about the mileage.

 

I think I’m just gonna buy a $25 boush temp gauge and plumb it into the return hose and be done with it. I saw a video on YouTube, if I can find the tee the guy used I think I’ll be good.

 

Your Jeep, your choice but those T's are all over FleaBay.

 

Be aware that coolant temp gauges are acutely sensitive to being in the correct location, and fully immersed in coolant

That means a aftermarket gauge in the return pipe will not show the same temp as the OEM sender/gauge

 

Plenty of clusters available and they swap easily.
