I have an alarm that only has the hood pin trigger wire and a shock sensor port hidden in the dash.

I'm gonna be getting a tilt sensor, a audio sensor and a back up battery.


Question 1. Can I splice a similar gauge wire into the hood trigger wire then diode the next end to the trunk trigger near the back seat?

and 2. Can I diode from the audio sensor blue wire to the tilt's trigger and get a different zone reading for both or will it be the same?

I have so many other wires for my eq, bluetooth mic and footwell lightning wire running close to the brain and don't want the tangle.


Thank

 

In theory yes it is possible, assuming that all the inputs use the same polarity.(All negative or all positive triggers) If that is the case and they are all the same, add a diode with the gray stripe facing the alarm brain on the wires of the additional sensors.

 

Make sure to cover the diode with heatshrink tubing or electrical tape. You don't want it to come into contact with the car chassis.

 

do not store anything of value in the trunk. lug nut key, spare tire, subwoofers anything. these trunks are sadly easy as pie to open even with an alarm

 

The key lock thing is already detached plus my nut key is nowhere a thief would look for it. my subs are gonna strapped. Btw the area I live in is full of patrolling sheriffs and nosy retired neighbors.

 

Easy peazy. You can absolutely use a diode, as pictured above. Tie it into the door circuit, not the hood switch, and you can do all at the kick panel. The purpose of the diode is simply to keep the door light from coming on while the trunk is open or vice versa. It will always show up as whatever zone you tie it into though. If you tie it into the hood switch without a diode, you will then get a trunk light when the hood is popped.

Consider a mercury switch for the hood as well, it's a lot easier to hide near the rear of the hood and doesn't look ugly in the bay.
