Tekonsha Brake Control Wiring Adapter - 2 Plug fits Toyota, Lexus

The Tekonsha Brake Control Wiring Adapter – 2 Plug for Toyota and Lexus vehicles is a plug-and-play connector system designed for seamless integration between aftermarket brake control units and OEM vehicle harnesses. This 2-plug wiring adapter eliminates the need for permanent modifications or splicing, allowing the brake controller harness to connect directly into the vehicle's factory port with a simple mated connection.

The adapter bridges the brake control unit output to the Toyota and Lexus factory wiring architecture, preserving OEM connectors and maintaining clean, reversible installations. Part number 3040-P delivers reliable signal transmission for brake actuator control in trailer braking and load-sensing applications. The lightweight design (0.3 lbs) integrates unobtrusively within engine bay or under-dash wiring runs. This connector solution is identified by Tekonsha's Plug & Play logo and is confirmed compatible with 2003–2009 Lexus GX 470 models in all trim levels, with broader Toyota and Lexus platform support across the specified years.

Vehicle operators and technicians managing trailer-braking setups on late-model Toyota and Lexus platforms benefit from this adapter's ability to streamline wiring consolidation without compromising factory electrical integrity. The 2-plug configuration is standard for modern Tekonsha controllers and is the preferred approach for vehicles where factory harness ports accommodate direct connection. Installation time is significantly reduced compared to traditional tap-in harness methods, making this adapter a practical choice for both professional fleet installations and field operator setups requiring quick connector swap capability.
