More about the product

Primary ISO Harness

The Aerpro APP0259 allows you to retain the factory amplified system in your Toyota or Lexus when upgrading to a compatible aftermarket head unit. The harness plugs into the factory Toyota plug behind the original head unit and converts it to 4 RCA plugs, which connects to the RCA inputs on the rear of the aftermarket head unit (front and rear). The harness also provides an ISO connector for power and earth connections. To simplify the installation process, add an Aerpro APP8 aftermarket head unit ISO harness which will connect from the aftermarket head unit directly to this harness.
