Hello all.This is my first post. I have a '68 427, 390 hp that i have owned for 27 years. I am trying to restore it. It is 1 of 380 that had a factory alarm system. I found the door switches and it has the key set switch, but the hood switch look like it was never installed. I this possible? I also look for the horn under the drivers side wheel well. No there. I checked my vin number and the alarm is factory installed.

I have no idea when it comes to those factory alarms. I just wanted to say welcome, and when you can please post some pics of your car.

I feel kind of bad. Lots of friendly people are saying hi but no one seems to be able to help with the poor guy's problem.

Hi, and welcome to the forum.

I've got a '69 with the alarm system. The hood switch should be a chincy little button switch with one yellow wire running all the way over to it from the fuse block. I may be wrong, but since it was an option, the yellow wire was not part of the standard wiring harness. There will also be a lone yellow wire running under the dash to power your door alarm switches.

As far as the horn goes, there should be a couple of wires coming through the rear compartment on the drivers side that follow your wiring harness out to the tail lights. I think there was a wire for the horn, and one for the key tumbler on the rear of the car.

But then I am only about 90% sure mine was factory installed as it does look so after market. Look for the lone yellow wires. Hope that helps.

Dave

Most know what the 69 system looks like, but the 68 might be different. Its so rare, I cant remember if I have ever seen one.

Wouldnt it be prudent to look at an assembly manual. I think that would give the information needed.

Welcome to the forum.
If you have the key in the back for the alarm and the alarm switches in the doors (the ones on the rear of the door opening, not the ones at the front edge) then your car must have had the alarm, theres no telling what could have been missed during the early days of production on the C3.
The horn should be behind the rear drivers side wheel well, just below the antenna. If th ehorn isnt there, then the wiring should be.
Just so happen sI have one for sale if you need one
