I have a 300TE. When I got the car, the wiring harness was disconnected to the alarm relay. I plugged it back in and with the system armed, if you trip it, just the lights flash, no horn. I tried the window feature and it didn't work. The horn will honk when you press the horn button. Any ideas? I would like to have the alarm system functioning. Thanks in advance.

Anybody???

I did a thread on this a while back and got no responses.

The alarm system has it's own horn, usually mounted on the left fender under the hood on the 124 chassis cars. You should check to see if the wires to the horn are connected.
