Wiring Harnesses

Compatible Trig products

These wiring harnesses are designed to be used with a Trig TY91 or TY92 compact radio. Each wiring harness includes connections for both the radio back box and the radio control head. Both short and long harnesses are identical, but the 1 metre length is ideal where both the controller and back box are mounted close to the instrument panel. The 3 metre harness gives more flexibility when mounting the back box away from the panel.

Frequently Asked Questions

Do the headphone and microphone sockets come with the cable?
Yes, they are already attached to the wiring.

Do the harnesses use shielded cable?
Yes, all audio lines are shielded.

How do you connect Trig wiring harnesses to the aircraft electrical system?
The wiring harnesses come with connections for power and ground. A circuit breaker as specified in the installation manual should be used.

I need to remove a connector to install the harness in my aircraft?
In most installations, simply connect the wiring harness to the Trig unit and stow any excess wire in a safe and tidy way. If you need to remove a connection D-Sub to route the wires through a tight space in your aircraft, we recommend that you use an inexpensive crimp removal tool.

1. Open the Controller D-Sub connector - this is easier as there are fewer wires in this connector.
2. Use a crimp removal tool to carefully take out each wire and its connected pin.
3. Route the cable through the aircraft in a safe method.
4. When complete re-insert the pins into the Controller D-Sub.
5. Check and test the connections are correct and working.

This avoids having to cut wires and retains the superior reliability that a crimp connector offers over a soldered wire.
