The Axxess T-harness is a basic and simple plug-n-play harness for easy installation of the AX-DSP (sold separately) for vehicle-specific applications. Most T-harnesses created by Axxess will either have a 4-pin or 8-pin harness, with the speaker wires pinned. If you are installing a 4-channel amplifier with the AX-DSP, leave these connectors disconnected. The only reason for connecting these harnesses together would be if the AX-DSP is being used for adding a subwoofer amplifier only. Some T-harnesses require additional wiring and/or installation steps. Refer to the following page for a pinout legend for the 20-pin harness, and also additional wiring and notes.
