Hello, I have an alarm system, with signal horn, 2 ultrasonic sensors plus control unit, connection monitoring for door, trunk, etc. I don’t necessarily want to drive the ZV and the starter to save work. It’s just about preventing someone from touching the car 🙂 My questions: 1.) I want to mount the signal horn (with integrated alarm control) in the engine compartment, but how do I go into the interior with all the cable tones. Is there a “hole” somewhere in the interior 2.) It is enough for my purposes to activate only the ultrasonic sensors in order to trigger the alarm, right? Or should I necessarily also connect the interior lighting? 3.) To display the alarm, the flashers also have to be connected. Do I close the intended cable directly to the indicator stick on the handlebar wheel or should I take the mega-long way back to the light bulb? The cable is no longer available. t very long.
