The iDatalink ACC-HU-ALP1 adapter allows you to connect select Alpine radios to compatible iDatalink T-harnesses. This extra harness takes the place of the harness that comes with your new Alpine stereo. It connects directly between select Alpine radios and the latest Maestro "Head-unit ready" T-harnesses so you won't have to splice any wires.
