The APP0258 allows you to retain the factory amplified system in your Toyota or Lexus when upgrading to a compatible aftermarket headunit. The harness plugs into the factory Toyota plug behind the original headunit and converts it to 4 RCA plugs, which connects to the RCA inputs on the rear of the aftermarket headunit (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 headunit ISO harness which will connect from the aftermarket headunit directly to this harness.
Please Note:
The aftermarket headunit requires 4 RCA inputs (front / rear).
