## What is TRIGGER ACS?

The Trigger Accessory Control System substantially saves installation time of your electronic accessories! Eliminate the need to run wires under the dash or through the firewall of your vehicle when running wires.

Our Bluetooth App will control on/off and dimming functions as well as flashing when used with LED or conventional lighting. It is simple to set up and allows for user customization. Use the app to “Trigger” lights from outside the vehicle whenever you might need to activate an accessory on demand.

In addition to the app, Trigger includes an RF remote control for activating installed accessories from outside the vehicle and dimming/flashing functions for installed lighting. In addition, two 30 amp and two 10 amp fused circuits with LED indicators notify you of blown fuses.

App Setup Instructions:

1. Ensure Bluetooth is active on your mobile device, and the Trigger Controller is powered on.
2. Once downloaded and installed, tap the Trigger icon to launch the app. Bluetooth pairing occurs automatically, there is no need to manually pair the App.
3. Once the App is running, tap the 'GO' button in the middle of the screen to connect to your Trigger Controller.
4. After a few seconds, the App will connect. Power, strobe, and dimming functionality will now be active.
5. Tap the 'Settings' icon to customize the names of your Trigger connected accessories. Tap 'Save' to save the customized names.
6. Tap 'Home' to return to the main App screen.

### 1/5 — Not pairing

*2022-06-11*

This app will not pair. It use to work but just stopped pairing. I deleted and reinstalled, still no use. Spent a lot of money to install this product and the app isn’t working. And the wireless switch requires regular battery replacement. Waste of money to turn my lights on and still can’t turn them on.

### 1/5 — Needs work

*2021-01-21*

I have the Trigger 4 system in my vehicle. It has yet to ever connect to the app. Disappointing

### 3/5 — Bluetooth

*2020-05-08*

App is not very responsive. You have to initiate a function multiple times before it actually works. The remote that comes with the unit works well, don’t understand why the app can’t work as well.

### 5/5 — Trigger Control

*2018-10-30*

App works great.  Always connects and functions.

### 3/5 — Connection is tough

*2018-10-09*

Took tons of tries, followed the instructions here and it finally worked. Until it didn’t again. Very spotty right now. BUT all would be forgiven if these issues were fixed AND you made it CarPlay compatible 😁

### 1/5 — Does not connect.

*2018-06-13*

App was updated 6months ago you could fix the iPhone Bluetooth connection issue.

### 5/5 — If you tried to connect manual Bluetooth

*2018-05-17*

Would not work. You need to launch the app then hit the go button and while its trying to connect hit the settings button. Then hit forget device and force quit the app. Reboot your iPhone then launch the app. Click the go button and you are all set! You’re welcome!

### 1/5 — Won't connect.

*2017-12-21*

This would be awesome, if it actually worked. I cannot get the trigger to connect via Bluetooth to my iPhone. Very annoyed. I tried to manually connect via Bluetooth in setting from my phone, but keep getting a notice saying that "Trigger not supported."

### 1/5 — Needs work

*2017-08-26*

Just installed this in my 13 Tacoma today. Had difficulty getting phone to connect. No instructions included.  Just hit scan. Seems simple. No indication of weather the phone has connected or not. Slide the switch... nothing scan again and again. Finally the slider turns on my light bar. Twenty minutes later. Nothing!!  Scan again and again. Still no response from trigger. The included switches work. However the ability to demo for customers from my iPhone was paramount.

### 4/5 — Good start

*2017-05-06*

Great product and good start with the app. Like the simple and easy to use interface. Suggestion, please make landscape available as an option. I've got an iPad mini mounted in my dash and this would be perfect to use to control the switches if they were landscape orientation.
