How to wire flashing lights and/or horn with aftermarket electric door locks?

[Tullyp]

I installed the A-1 electric door lock kit on my 2022 Gladiator and works great, but A-1 gives no advice on how to wire horn or lights to alert arming or disarming. I want one or both, but don't know how to wire these to the Avital 2101 alarm controller. Anyone know what wire to tape on horn and for parking lights, and if need resistors or diodes? I have searched internet, but can't find anything definitive.

Have you tried to contact the company that makes the Alarm Controller? If the company that sells the kit provides no information, it may not be easy or possible. I would expect that to be a common request, and would expect the kit documentation to address it.

A-1 uses the Avital for multiple kits so they won't get into that much detail with connections to a specific vehicle. Power to battery, ground to ground, and provided wiring harness to lock solonoids. Avital, that makes the alarm brain, will only communicate with a licensed installer.

 

[Mr._Bill]

You could use a relay (or two) triggered by the lock solenoid to activate the light and horn circuits.

The Avital has a wire dedicated to trigger the horn and a wire to flash the parking lights and I know I may be able to use a relay, but don't know what wires to tap into. Also, other threads I've read hint at the need for diodes and resistors to not mess up the canbus. I'm hoping someone on the forum may have installed something like this before.

 

[Mr._Bill]

If it has wires to trigger them, you would not need the relays triggered by the lock solenoid. You would use a diode between the trigger wire and the circuit to prevent voltage from being fed back into the alarm controller.

Mr_Bill, Thanks for your responses. I understand what the diode would be for, but more worried about the grounding or + power (optional) of alarm horn circuit to the jeep horn circuit. I don't know If horn is ground or (+) power activated, or what wire to tap (and where).​

​

For lights, I know alarm wire provides (+) power in bursts, but again don't know what wire to tap, and if it can cause problems with jeep wiring.​

​

I guess I'm just "chicken" to take a chance tapping wrong wire and messing up something. Still hoping someone has done this already.​

Anyone had any success with connecting these options

Jtmoney01,
I brought to local car alarm installer. Great deal, $70, and they worked on it for several hours. They installed a relay and now all lights flash (success), but could not get horn to work consistently (ok). If you have this lock system my best mod was installing a switch on lower dash to activate auto locker wire on alarm. Can lock or unlock all doors from inside without fob and relock all doors if I needed to unlock one door after start.

 

[Jtmoney01]

That switch sounds interesting. What kinda switch you use and which wires did you connect to

Bought a switch panel on Etsy that fit in lower center console cubby:
https://www.etsy.com/. Can't find my exact one anymore, but any two way switch will work.
Wired one wire of middle switch on panel to cig lighter power and other wire to lock activation wire on electric door lock alarm box. Switches have blue led when "on" so switch up has auto lock feature "on" and all doors lock at start, but flip switch "off" and all doors unlock. Switch back "on" and all doors lock again if car is running. Only difference with factory is it's all doors instead of each door separately, won't lock all doors while car ignition is off (but use fob for that anyway) , and only can reach switch from front seats. All passengers still have manual control of their door locks individually.
