1972corvette454

Need your help please.
I own a 1972 Corvette 454 Four Speed with air.
I took photos of my compartment where the Jack is stored.
There is a relay not sure the purpose, a 2 white wire and a 1 Yellow wire 2 prong connector that is supposed to plug into a______?


Thanks

Flasher for the alarm

Thanks

and the other relay its purpose?

Just use a standard turn signal flasher.
The other relay is the "hold-in" or locking relay for the alarm.

I would replace them both simply because the relay can go bad and drain the battery. If this happens, I'm willing to bet you won't even remember it's back there and a potential source for the drain.

We had issues in a 76 we built. Car had a new harness installed so we knew the wiring wasn't hacked. Took us a while with an ammeter to track the drain down. Turned out to be that relay.

Yup, exactly.

Where to get these 2 relays then? Thanks

Autozone.........ask for a turn signal flasher and a horn relay for a 78 Corvette.
(Not sure that you need the relay.A correct numbered alarm relay could cost you big bucks,why dont you try yours and see if it works.The horn relay for the 78 will replace the alarm relay for the 72 but you might have to switch 2 wires in the connector but I dont think so.)

I have a 72 and never really looked in the back compartments yet... is there an alarm such as anti-theft alarm that normally comes on these things?

voat

VTcivil: The anti theft alarm was standard in 1972, you should have a key switch on the back between your tail lights.

I have the same key hole on my '73 and it opens the trunk.
Did the 73's come with an alarm system?

wjsullivan

Trunk?

Yes, that should be how you engage the alarm. Later models have it over the driver side front wheel.

VTcivil

alright, i can't tell if I'm being messed with or if there is some truth to any of this... ??

...Roger...

Yes your 72 came with a factory alarm.
Bob was joking about the trunk,he's such a kidder.

Bob Onit

Bah.... you blew my fun

I almost pissed myself when I read the post by VTcivil

Sorry all, couldn't pass this opportunity up

VTcivil

factory alarm... hum, never new. how was this alarm enabled/disabled ?

Yes, I knew the trunk thing was a joke.. a good ole trunk in a C3 joke, you gotta love it!

...Roger...

Its enabled/disabled by the key in the back of the body that looks like a trunk key.

VTcivil

I've got a 72 and there is no such keyhole in the tail. All that is between the tail lights is the corvette letters...

Check near your front driverside fender for another lock.
