Gentlemen!
I posted several years ago about wanting to add a door lock switch in the rear cargo area of my 98 XJ but never quite figured out how to do what I wanted.
I was looking to install a switch what would allow me to lock or unlock all doors from the back hatch. I don't have a keyless remote and I have had countless times where I would unlock the rear hatch to get to a few things just to leave my self wishing that there was an easy way to unlock the rest of the doors. Or, on your way out when you need to grab something, it would be nice to be able to close all front passenger doors (unlocked) and then go to the hatch and grab something before departing and do one final lock action from the hatch itself. Before, I would lock all doors and take my key to the rear hatch, unlock it, grab the item, then lock it back down. This would also be handy even if you had keyless so you don't have to fumble for your keys after throwing them in your pocket. So long story short, I thought this would be a nice addition.
Well, I finally figured it out. All you have to do is run ground through two momentary switches from your chosen location in the back hatch up to the front door lock/unlock signal request wires. In my year and I'm assuming at least the 97 to the 99, the wires are light blue w/ red stripe and dark blue. Essentially all you have to do is ground either of these wires individually for either a lock or an unlock signal ground pulse.
I used a self tapping screw to pull ground right by the switches, ran one wire to each switch and then ran the other end of each switch to the lt blue and red wire and the dark blue wire. I do have the keyless entry module built into the front dome light and was able to very easily tap into the two signal wires there. If you don't have the keyless module in your roof, then you'd have to get up to the main loom in the passenger kick panel.
This is a fairly easy mod and one that I am glad that I finally figured out.
I got lazy when tying into the lt.blue/dk. blue wires. Since I don't have or use keyless, I just unplugged the connector and stuck the signal wires into the female portion of the plug. If you would like to retain keyless, just splice into these wires behind the plug.
