Yea it is pretty simple,all you need to do is replace your radiator with a radiator from a 91 and newer,and replace the heater control valve with a 91 and newer.
Remove your coolant bottle and replace it with one that is an overflow tank,just a normal overflow bottle and run hose from cap to the tank. I did mine for about $50,everything came from the local jy.
Here is a couple of pics that show what mine looks like now.

I did it on my 90. One of the best upgrades you can do to boost reliability. I bought a new 2 core all metal radiator and new hoses and got the heater valve and thermostat cover at the jy. Just look at the jy xj to see how it is put together. There are a lot of write ups on the internet about it if you get stuck.

There are three temp sending units on a renix XJ. One for the computer, one for the gauge and one(the one your talking about) for the electric fan. Read the article again, it mentions an adapter that moves it to the lower radiator hose or installing a manual switch. I've also wondered if a '91-on t-stat housing will work on a renix, or just drilling and tapping the renix thermostat housing to accept the sending unit. If you go that route, welding a boss on the housing would be a good idea.
