Hello everyone,
I have been wandering what the open wiring harness under my driver's seat was used for, and I finally figured it out. It is the autolock harness. For ATX SHOs, this harness allows the doors to automatically be locked when the car is taken out of reverse or out of first gear when weight is sensed on the seat. For some reason, MTX SHOs come with the harness disconnected. To make it work is easy though. Just take about 4 inches of standard electrical wire and attach a male end connector on both sides of the wire. Then plug the male connectors into the plug, which closes the circuit, and your done. The only thing left to do is to turn "Autolock" on. To do this, enter your keyless entry code into the panel and within 5 seconds of that press and release the 3/4 key while holding the 7/8 key down. Then enjoy automatic locking for your SHO. I believe this only works if your SHO came with keyless entry, and it may only work on Gen II's. If your battery is disconnected or voltage falls below 11 volts, you'll have to re-activate the "Autolock" feature through the keyless entry pad. Enjoy!

Only thing is, you have to hit reverse (just like it is activated in the auto...you pass reverse and it locks) in your MTX once started (every time you start it) for it to activate and autolock the doors.
