    Anyway briderx and i became close friends after meeting here. I was even in his wedding as a groomsman. Unfortunately he Sold the XJ a few years ago. the new owner promptly ripped out the computer and has reinstalled all the stock components. briderx has said that while it was a fun project, he won't do it again.

    Mine on the other hand has never been finished due to having constant hardware issues. first the motherboard had no audio, the second one would crash for no reason. I then bought a new MB and so far its been ok, but i have had power supply issues and then hard drive issues. And now i'm back to revisit the monitor problems again. I have no intention on EVER selling my XJ so i will get it finished once i figure out all the problems. I really need to break down and buy a new monitor, and SSD.

    It's good to know someone is still out there working on this! I fear the hardware issues, an so I'm currently avoiding them.... I am planning on using a used laptop as the test environment, sitting on the passenger seat and running USB and VGA to the dash from there, and worrying about Real Hardware after I figure out the dash configuration. Baby steps for me, starting with the most difficult and most important part first. Naturally, because of the nature of the '91 dash, it's a bit intimidating, and I havn't left the planning stages

    I guess my real question is this: What are you doing about the mechanical HVAC controls? I'm tempted to put my screen lower, under the HVAC, under the vent, just cut out the coin holder and ash tray and mount it in the hole created. As for the hole left by the original stereo, I would consider using one of the older Logitech 5 channel computer speaker systems, and mounting that control system up there. BUT, moving the HVAC controls would be a whole lot cleaner, so I'm curious about your approach.

    I'm afraid this is gonna more of a teaser than a solution. But i actually made my own HVAC controls and relocated them to the now blocked off vent hole under the original HVAC controls. I used 2 6-position rotary switches from radio shack for the fan and position and designed a servo controller and installed a servo to operate the blend door. The fan position was easy 1 pole for each speed, wired to a relay.

    The position was another issue. I found a electric ported vacuum switch by searching here. it was used in some lat s-10 blazers with auto-HVAC. its basically 1 vacuum line a 5 or 6 (can't remember) solenoids that trip individually. i ran these to each of the vacuum diaphragms to work to mode doors (floor, vent/dash, defrost etc.) then using a combination of diodes and switch positions i managed after ALOT of trial and error to get the following positions; off, dash, dash/floor, floor, floor/defrost and finally defrost.

    I DO have pictures of this but i did not document the wiring or vacuum schematics i will try and post them later if i get a chance.

    the only thing i haven't figured out yet is the a/c switch and the heater valve. the a/c shouldn't be too hard. but the heater control valve requires vacuum to shut it off, thus rerouting the coolant back to the motor, this lets the a/c work more efficiently. It normally shuts when the hot/cold lever is all the way to cold. i may have to install a push button for this.

    I would be interested in seeing this as I also have a '96 Grand Cherokee.
