I just found the coolest thing in my car! After reading techsoft, look all over the web and this site I thought the locks were going to be a nightmare. Out of boredom I went and tore my car apart, if you don't know, saturn are held mostly together with clips. Poking around the dash I came across the keyless moudle and I found my lock wires w/ driver door only lock wire too, trunk release, door trigers, horn, etc. All in a easy to tag postion, just take off the two 7mil above the passenger airbag and pull the entire uper dash off. Behind the insturment cluster and to the right if facing it is where you can find it. I tore my entire remote start and window moudle out and I'm in the process of rewiring it all so its all up there, theres a lot of room! Just thought I would share my find, hope it helps someone out in the future!

Notes:
NOTE:  This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with.  Use DEI part 555t or 555L.  *1 Use gray/black for the drivers door and lt. green/black for the passenger door(s).  The gray/black is located near the diagnostic plug harness under the drivers side of the dash, and the lt. green/black is located in a black 24 pin plug behind the fuse box in the center console.  Use both wires and diode isolate each.  *2 Ignition module is on the center front of the motor. Can also find tach at the PCM located behind the battery.  *3 On vehicles without power door locks go to the light in the trunk. On vehicles with power door locks can find the wire in a gray 68 pin plug behind the fuse box in the center console.  *4 Low beam is high current negative, must use relay.  *5 The lt. green key sense wire at the steering column must see a ground during remote start to keep the SERVICE light from coming on.
