The harness connector does not include the car harness box and only ships with the wires and connectors needed to install an existing car harness into another car.
Give your car harness more flexibility with another harness connector. The harness connector replaces the connector in your existing car harness for use in multiple cars. Already using a comma device and car harness in your Toyota and want to try it out in your Honda? Simply swap out the connector in your car harness, install, and drive!
For a harness connector with all the wires and only the 26 pin molex connector, choose "Development".
Buy it here or build it yourself. Harness connectors are open source.
