Understand the double-sided key thing. Deal with that all day. What I'm referring to is the fact that the trunk lock has a reversed keyway which in design doesn't allow you to insert your ignition/door key. Hold your trunk key beside your door/ign key and you'll see they're mirror imaged. I presume that's ford's original "valet key" design so the person with your door/ignition key couldn't get into your trunk. If one of your ignition/door keys will fit into the trunk plug then either the plug has already been converted (good news for me...less research and tinkering) or you've got an incredibly unique ford. I just found an old trunk lock off an early 80s cougar, now I need to dig up a door lock and see if the plugs will interchange. Man, that would be awesome.
I've had customers that had those made. The double-cut keys. I've had 2 people break keys into the doors because they kept putting the keys in upside-down. That would be my only word of caution.
My solution for old fords when a customer brings up this issue is to get a second headlight dimmer switch and mount it high on the floorboard and conceal it beneath the carpet. Run your power lead to your starter through this dimmer switch so it will kill power to the starter when you step on it. Simple system which doesn't require a full alarm. This trick has been around a while and has stumped many a novice car thief (or teenage child). Of course, the pros will find away around it but there's usually no stopping those guys anyway. My general rule when it comes to home/auto security is if you slow them down they'll usually move on. problem solving takes time and every second greatly increases the risk level of a vandal/car thief. Aside from that, good insurance is your only sure defense.
lol....good point. I like to reply to unresolved threads even if they're ancient in order to help out anyone searching the topic.
