Re: Installing a ZJ/XJ overhead console:

Hello Zluster!! I would need your help to plug the Air Temp Sensor on my over head console. I have a Cherokee XJ with a ZJ computer. Everything work but I have a problem to find out where to connect the sensor. Lights are working properly, compass is powered but no Temp reading. I tried to connect the two remaining wires, purple and white/black but of course it would too easy. Would you mind to help me on that?
Thanks a lot in advance!!

Re: Installing a ZJ/XJ overhead console:

My 96 XJ came with the overhead console. It is quite handy. If I didn't already have one though, I would probably keep my sunglasses on top of my head and stick a thermometer and a compass to the dash with superglue if I wanted the features.

Re: Installing a ZJ/XJ overhead console:

anyone had success with this modification on older cherokees? mine is a 92? just wondering if anyone got it to work on the HO cherokees

You need the ZJ BCM. You connect the temperature sensor to the BCM, and then connect the purple and white CCD bus wires on the BCM to the XJ purple and white wires. Connect the purple and white from the XJ, the overhead console, and the ZJ BCM and everything will work correctly.

Connect the wires like shown in this photo:

No, that is the ZJ BCM, the XJ does not have a BCM, so the temp sensor connects directly to the XJ trip computer in an XJ. If you use a ZJ trip computer then you need use a ZJ BCM, connect the temp sensor to the ZJ BCM, connect the CCD bus(purple and white) from the ZJ BCM to the XJ. That will pass on the temperature sensor signal to the overhead console, and the overhead console will work 100% like the factory unit does this way.

If you just connect the ZJ console up without using the BCM everything will work except the outside temp, you need to do the ZJ BCM hoopla to get the outside temp to work.

One guy started to do this on a 92, then never posted back.

The older XJ's never had the gas mileage functions, the overhead console just had the temperature and compass. If you were going to do this for an older(1992) XJ you should get the caravan console and trip computer, and then go from there, the caravan console has dedicated wires for the gas tank level, headlight dimmer, etc that you would need to tie in. At the very least the temperature and compass will work, but you might get the gas mileage functions to work.

PM me if you are really serious about it.

Re: Installing a ZJ/XJ overhead console:

It's not 100% certain that getting the caravan overhead console which does have MPG functions will work in an older XJ. It's really only speculation at this point. The ZJ's of the same era have it, so the main question is whether or not the XJ's of the same era will transmit the information necessary on the CCD bus for the console to do the MPG calculations.

To do this on an older cherokee either the minivan console, or an older (93-95) ZJ console would be what you wanted. You then need to tie in the various inputs needed.

Boilermaker never posted back with his results but a different ECU, or a ZJ BCM, or a ZJ ECU etc is probably needed to get this to work on an older cherokee. I can't say for sure and I won't be the one finding out, I don't own any older cherokees.
