I've been looking around at the most popular corvette parts websites, but dont see a complete Alarm system kit for a 72. I see individual parts sold separately. Does anyone make an OEM style complete kit?

PS I did a search here and found a link to a good installation progress tutorial, but didn't see mention of what I'm looking for.

TIA.

 

I don't know the reason you are looking for an alarm kit for your 72, but will share some experiences that I have witnessed over the last 40 or 50 years with my involvement with corvettes. An alarm is usually a waste of money If someone is determined to steal the car, they can do it easily no matter what alarm set up you have. Plus, when was the last time you stopped when you heard a car alarm go off? I will assume ( but I might be wrong) that the car is secured in your garage or yard at night. If it is in the driveway, just park another car behind it. The most effect anti theft set up is a kill switch of some kind. Either a battery disconnect, or if you have an electric fuel pump, a switch cutting off the power. That will work on wherever you park the car. On a lot of these cars that are still stock, with an OEM ignition system, the best thing I ever came across was putting a kill switch into the wire going to the ignition coil. Hide the switch somewhere that is not obvious ( there was a guy on this forum I believe that wired it into his cigarette lighter). That cutting off the power will stop any but the most determined thieves. A long time ago when I had a C2, the bad guys would shove an ice pick thru the gills ( on a 67) and punch a hole in the battery. So much for an anti theft system, which now doesn't work) Then they would just push the car out of the driveway, hook up to a tow truck and be gone. Even C6's are not immune from a determined thief. They just work around the electronics and bypass the key fob. My advice would be skip the time and money of some type of alarm system and just install some low tech power shut off.

 

Thanks for the advice. Mainly, I was looking at it from a stand point of having everything on the car and working that came from the factory. Even new cars with On Star and other security measures aren't immune from theft, so I wasn't really looking at this for anything other than what I've stated.

 

I redid the alarm on my 72 also. I had the car judged, NCRS last year.

The alarm system is very simple and basic. The key switch and "special" horn are very expensive if you need to replace or repair them.

The flasher and relay are easy to fix and replace.

As far a I know there are no kits to repair / replace the system.

I would see if the horn and key work, or shop for them before you tackle the system.
Good luck with the project.

 

Maybe something here:https://www.google.com/search?q=trou...h=468&dpr=1.82

 

Thanks. My car isnt numbers matching so no entering any contests lol.....and the interior was redone at some point before I bought it. Its pretty much stock looking, but missing some stuff here and there like the wiring for most of this is missing. Ill check for a horn and relay this weekend. The door ajar switches are missing as well.

 

eBay and patience will be your best FRIEND. I regularly check eBay for C3 NOS (new old stock) parts for my 73. AFTER Reading all the horror stories, plus my own experience, a lot of the Corvette Restoration Parts are not very good. You will need a 72 AIM and a Chevrolet Service Manual ( used ones on eBay ), and then you can start your search. The vendors sell parts, but not the complete system. The Service Manual will have the wiring diagram, but I am not sure if Lectric Limited sells the wiring harness. Also not every model year has the same factory alarm, Chevrolet always likes to make changes. Welcome to the HOBBY.

 

I have a 1971 that came with an alarm but I never used it. I found another nearly foolproof anti-theft/hijacking system that has never failed me. I inserted a 30 amp inline fuse under the hood in 12 gauge wire from the ignition switch to the starter solenoid. (in my '71 its purple) Below that (between the fuse and the solenoid) I spliced in a long 12 gauge wire which I ran through the firewall into the passenger compartment and grounded the other end. (Attached to the dashboard support brackets.) Somewhere that was convenient in that wire I cut it and attached a spade connection (male on one end and female on the other.) which could be slipped back under the dash and out of view.. (A switch could also be used and mounted in a hidden place somewhere.) When the spade is connected, if someone tries to start or hotwire the car the connection goes to ground and blows the 30A fuse. The only way to start the car is to unplug the spade connection (or turn off the switch) and replace the fuse under the hood. When starting the car, I would first disconnect the spade connection (or turn off the switch) and after it was started I would reconnect the spade connection.

Since the 12 gauge wire is only used to start the car, even if hijacked I could turn off the engine and give the keys to the hijackers who wouldn't know about the connection and be unable to start the car.

IMPORTANT: Always carry extra 30A fused in the car.

Hope this helps.

Whenever someone asks a question about alarms someone will come back with it being a waste of time and money but I'd rather have it than not have it. I've put several alarms in my cars over the years and will put one in my 81 year hen I get a chance. I don't need all the wiz bang options that modern Alabama me offer today,someone touches the car the alarm goes off,they do happen to get in the car they've got to get it started by bypassing the alarm. This takes time and a thief wants to spend the least amount of time as possible stealing something. As stated,if the thief wants something they are going to get it,I'm just not going to make it easy for them.

 

I have the ultimate kill switch setup I made for a 75 and offered it for sale,nobody was interested.
