Theft Deterrent System?

[mojo69]

We just bought a '94 Camry. I disconnected the negative terminal and installed an aftermarket Radio.

When I reconnected everything, I went to crank and it did nothing. Then in 5 seconds or so, the horn starts to sound repetitively like there is an alarm or something. As far as I know, there is not alarm that goes to it.

Is there a factory alarm installed on this puppy or is it the factory theft deterrent system?

PS: It does the same thing with the factory radio reinstalled.

I would have to say, yes, you do have an alarm. If you have a factory one, you would be able to tell from the center counsol. Right next to the hand e-brake, there should be a 2x1 inch black rectangle with a light in it.
