Here is some more info on the overhead console install. You don't need the wiring harness to install the console. If you have the Dome light with the Keyless entry computer in it which you will have whether you have the option or not. It is real easy to wire up the console. You just have to run 2 wires to the temp. sensor and one wire to 12+. I used 2 trailer harnesses to make it easy. I won mine on ebay and it has been working perfectly for over 6 months now. Here is the website.

98 o/h console into a 97 sport...
--------------------------------------------------------------------------------
Well, first of all let me say thanx to Jeepzz for all the helpfull information on this topic. I am not going to repeat all the info that he has given me as it would take me forever and is already available on here (threads called "wiring diagram for overhead console" and "another overhead console thread"), but I do have some findings of my own to put on here in addition to jeepzz in case it may help others.
I recently put a 98 o/h console with a 98 harness into my 97 cherokee sport. For some of you, this can be a challenge depending on what year jeep you have, and if you have keyless entry, and what year your console and harness came out of. This info is for ppl who are taking a 98 unit with keyless entry and putting it into a 97 with keyless entry. Here's how..
1. Disconnect the battery.
2. Remove your kick panel on the passenger side, glove box, and A pillar shrouds. This will probably require unscrewing the plastic finish under the far right air vent on your dash beside the glove box as it is a bit tricky, and unscrewing your O sh*t handles. These have hex nuts.
3. Moving up, remove the sunvisers, and their clips, your dome light, and finally the little plastic dome in the front centre of the headliner. Behind here you will find your keyless entry electronics. Keep this.
4. At this point your headliner will be loose, and you can start removing the wiring harness for all the stuff you just took out, it all just unclips.
5. Once you get down to the door, go down to the junction block and find the connection for the keyless entry. It will be located right at the bottom and is a bigger pigtail. Leave a couple inches, and clip this one off.
6. Next, unplug the wiring for the lights, it is a little 3 wire plug with pink, yellow, and black wires coming out of it and is located at the top right corner of the junction box if you were looking straight at it.
7. Pull the harness out through the side of the dash. Half way there!
8. Next, take the new harness, and identify the keyless entry pigtail. Do this by locating the computer data plug. It will be located behind the glovebox on the lower right hand side and will be empty. Find the pigtail on the 98 harness that fits into this, and clip off the other pigtail of similar size. (keyless entry)
9. feed the two pigtails and the keyless entry wire through the same area you pulled the 97 harness out of.
10. Attach the 97 pigtail for the keyless entry and plug it in. Plug in the lighting pigtail, and then plug in the computer pigtail.
11. Route harness up the A pillar, clipping it in along the way, and run it up into center of the headliner. Be sure to pull the plugs for the visors through the headliner. The driver side is tricky for this, you might need to lossen the a pillar assembly enough to get the headliner to come down enough to feed it through.
12. Now comes the fun part, cutting the headliner. The mounting bracket simply screws into the holes from from your dome light. Cut the headliner so this will fit, but don't over cut. Then cut the hole behind for the console tounge to fit into.
13. Now you need to replace your keyless entry circuitry from your pod into the overhead console, otherwise your keyless won't work. If you have an aftermarket alarm, this might not be needed, your alarm a try to see.
14. Once you have replaced the keyless circuit, go ahead and do a test. First connect your console, then the battery. You should note the lights come on. Now try your keyless to see if it should work, and turn your ignition to the on postion to check the computer dislplay.
15. This is where some people have trouble, as the keyless and lights work, but the computer doesn't. It may NOT be a power supply problem. IF you have a dislplay, re-assemble everything, you are done. If not, read on...
At this point you need to do a power check. First check all your fuses. The fuse you need to check is #17 under the hood, and is a 15A. Then check #17 in the kick panel. If this is good (fix it if it is not), turn the ignition off and disconnect the battery. Check for continuity in the gound curcuit cavities in the o/h console harness. (these are points 1,7,and 12, or the top right and bottom two outer pins left and right). If that is ok, re-connect the battery and check for power in the harness. It is in points 2 and 6, or the top left point, and the 2nd in from the right (top). If you have power here, you do not have a power delivery problem. However, if you want to be a keener, you can also check to see that there is power being delivered to the computer by testing for power in the little harness directly connected to the computer. Power is the second point in from the right. If you have power here, you do not have a power problem.
Next, and this is the part that most don't know about, you need to do a self diagnostic test and reset.
1. with the ignition off, press and hold the step and US/Metric buttons simultaniously.
2. While holding these, turn on the ignition.
3. Continue to hold these down. The computer should come on. Continue holding until and during all of the lights turn on. If they do not come on after after 5 seconds, your computer is bunk. If they do, the computer does a self diagnostic, resets, checks CCD data, and will return to normal operation right after the test.
4. If it fails, the computer will display fail, and the unit is faulty. If it displays CCD, you will need to go to the dealership as they will need to hook it up to a comupter.
5. At this point, if it is working, you can put everything back together.
Well, that is about it, I hope this helps some of you out. It has been suggested that someone combines all of these threads into one, but i just don't have the time. However, if any of you need more tech data, I have a bunch and can probably fax it to you if you need it. Cheers!
I think the other earlier posts answered most of the other questions. The Temp. sensor runs about $20 at the dealer.
Good luck
