Hi guys

I was wondering if I could make a fuel pump killswitch with a 2 way switch to the pump and to the horn



kinda like this:




The idea was inserting the switch in the circuit from the main relay to the pump, and if the switch was selected for the horn, the main relay, instead of powering the pump, would power the horn.

I have a simple spare horn from an old suzuki i could use, so i wouldnt mess with the original one.

What do you guys say about this? Easy job?

 

Oh I see, try and steal the car and get blasted with a horn. I like it!

Just make sure the switch you choose is rated for the correct amount of current on that circuit.

 

Yap, and probably the horn would be inside the car to blast the thiefs ears

My only question is ... is there any problem directing the power from the main relay to the horn, instead of the fuel pump?

 

Do the kill switch and install an alarm with options (proximity sensors, interior siren, etc).

 

You will just have to make sure that the horn uses close to the same amount of current as the pump.


What I have done before for customers is use a factory switch that either doesn't work(defrost) or is for an option that your car doesn't have. Example is installing an OEM foglight switch in a car that does not have them, and utilize that switch to trip a relay that cuts power to the fuel pump. Super stealth.

To be honest, alarms are an ok deterrent for smash and grab type scenarios, but a simple alarm isn't going to stop a pro from driving off with your car.(Well, maybe it will discourage one from continuing to try and take the car if it's not working out for them for whatever reason lol)

 

Most Hondas/Acuras are stolen, not vandalized. And they are stolen because the owner has the basic alarm (keyless entry, open door trigger, etc.) and are so easy to defeat. The alarm module is stashed away underneath the dash, visible to anyone who looks for it. Also, most car audio shops charge around $50 for each additional option installed, which should be a crime itself.

 

When I did my stealth install I used a variety of these methods:
