    easy mod to do yourself. I used OEM part# 3W7Z 9B242 AA retail $15.58 or you can use a momentary push button switch (McMaster Carr P/N 6915K22 or Radio Shack Cat # 275-646), and solder two leads to it.

    Next, Squeeze the sides of the glove box and it flips down. This will give you access to mount the switch. Drill a hole in the glove compartment box. Note there is a metal bar behind the right side of the glove compartment box. There is one spot that has a hole in it. Drill the hole in the plastic to match up with this hole. My button was 1/2" so I used a uni-bit that went up to 1/2"

    Remove the retainer nut from the switch and insert the switch and the leads into the hole. Thread the leads through the nut and onto the switch and tighten the nut up. Next, attach one of the leads to ground. I loosened one of the ground bolts all ready in the glove box and attached the lead to it and retightened.

    Next pull off the kick panel on the passenger side, just lift up on the cover and pull off the cover. Find the large wire harness and unwrap enough of the tape to reveal the wires. Find the skinny White wire with a pink stripe. This is the one we will be using. Carefully strip a small piece of insulation off this wire without cutting it. Strip a piece of insulation off the remaining lead from the switch and tightly wrap it around the exposed copper on the White/pink wire. Test your switch, You can solder this connection if you’d like or just tape it up really good.

    When finished, rewrap the wire bundle with electrical tape and place it back as it was. Replace the cover and the glove compartment box.



    Note that if the switch you chose is too big, the trunk might open sometimes if you slam the glove compartment box or if your knee hits the corner of the glove compartment door.

    If this is a problem, replace the rubber bumper on the glove compartment door with one that is a little larger and made of a harder rubber. Ace Hardware or Home Depot should have these.

    I can't take credit for the write up, I got it from this link from a fellow S197er,
    he has great pictures of the install, I just opted to go with a ford OEM switch instead of a aftermarket.
    here's the link http://www.cherod.com/mustang/HowTo/TrunkRelease.htm

    Yes, very nice. Thanks!
    To me it seems one could recess the switch a bit so the glove box closing would not open the trunk.

    You could also mount the switch in the center console, where that e-brake access cover is. Some people use that to mount a switch for their door opener. You could do the same with this.

    Don't know if this has been done before, but what if you took a spare key FOB apart, and mounted the tiny circuit board in your car, with a custom cover or something? ? You could have a trunk release AND a door opener panic button....AND it's wireless....:shrug:
    (or, you could just use the one ON your keychain, dangling from the ignition!)

    Very cool. I still don't get why Ford didn't install one of these from the factory! What a novel idea.

    i'd mount it under the driver side dash so you wouldn't have to open your glove box to get at it.

    Yes, trunk opens with the key fob car running - just not when the car is moving, you must be stopped!

    Ford used to put one in the glove box. I'm sure they saved a quarter or so by eliminating it.

    Well, if you think about it, it's not needed with having key fobs now. When you're in your car, your keyfob is right there, hanging from the ignition. That's more convenient than opening the glovebox. I'm sure they did a survey and found that the majority of people were using the keyfob and not the built-in button, so eliminated that.

    I have owned Mustangs forever and noone ever surveyed me. At one time they did not all come with remotes.
    I liked the button for opening the trunk when I needed something and did not have my keys on me.
