I was looking through the assembly manual last night and it has a very good drawing of all the parts behind the key switch and how to put them together. It is in black and white and does not state which color of wire connects to which lug on the back of the key switch. Anyone able to help me?

I don't think it matters since the switch is just a simple single pole on/off thing. But I could be wrong....

There should be a pink wire, and an orange wire(hot from fuse panel) connected to the key switch. Doesn't matter which goes where on the switch....it's just an on-off deal there. 
My '74 has never had the "anti-tamper" switch on it, under the key switch. The wiring is there, but the connector has been whacked off, and the wires taped up. One of these days, I might put one back on it, but the alarm works without it.

Victory! Horn's not installed and I couldn't test since kids are asleep in room next to garage, but everything appears to work now. I have voltage at the horn contacts at the right times and no more. Tested all the triggers and they all work. Greg , it's really not too bad - pretty simple system. Good luck!

For those times when you don't wanna disturb anyone with the horn, you can hook a test light to the horn connector. It should "flash" the same as if the horn was tootin.

Yep, I was just using a light bulb to make it flash. (Test light would be better, but I seem to have misplaced mine). I really need to test the horn itself though in the circuit, before I go to the trouble of reaching up in there to install -- only want to get the fiberglass slivers in my arm once more, if you know what I mean...

I tested with the real horn tonight! Remembered to do it before they went to bed. Had all three of them watching me and they thought it was hilarious. Mom was at a meeting for school but we had to "test" again when she got home. She practically jumped out her skin: "Holy 
that thing sounds like a sick elephant!"
that thing sounds like a sick elephant!"She's right - that horn does sound pretty bad, but it's loud and obnoxious and it works so who could ask more of a 37 year old factory anti-theft system!
Sorry for the three different posts tonight, but had to share!

Drove the Vette to work yesterday (beautiful weather for early June here in the Pacific NW) and actually set the alarm when I parked it. Didn't catch any bad guys but I sure scared the 
out of myself when I forgot to disarm before I opened the door! Gonna have to remember that when I use it! The good news is that it appears that my battery drain issue has been completely resolved now.
