2014-2019 Tundra Sony 4000 Installation Guide
2014-2021 Tundra Sony 4000

By: Cliff John, Trail Grid Pro

This installation guide is intended to be used to assist you during the installation of your

2014-2019 Sony 4000 Tundra Plug and Play Bundle from Trail Grid Pro.

Installing your bundle

Use our 9500ES Install video as reference. The disassembly and install of the body and dash kit will be the same. 

1. The Body – Consists of the head unit, silver dash kit and our custom wiring harness.

  • Make all your vehicle connections as noted in the document below. We’ve drawn a red box around the vehicle connectors you’ll be using for your installation, which are the 4 factory looking connectors from the Maestro RR module.
  • All the plugs are keyed plugs, which means they only fit their match on the Toyota side. All you’re doing is matching plugs – it may look like a lot of wires but it’s simple.
  • Small Yellow Clips: Please use the small yellow tab clips we supply in the bundle to attach to the tabs on the back of our dash kit. They are more robust than the factory clips and hold our bundle in place better when installed.

You Will Be Connecting:

4 Connectors From The Maestro Harness

USB Retention Adapter

Factory Navigation Adapter

Sony Microphone

AM/FM Radio Adapter

Sirius XM Tuner (If Selected)

  • DO NOT POWER ON YOUR HEAD-UNIT BEFORE ALL CONNECTIONS ARE MADE. This will cause an error when the Maestro RR module is trying to initialize to your vehicle.
