About this product
Upgrading your car audio with an aftermarket touchscreen can quickly become a complicated mess of tangled wires. The iDatalink Maestro ACC-HU-BOS1 head-unit adapter changes that by eliminating the stressful, time-consuming task of matching, stripping, and crimping dozens of tiny radio wires together. Designed specifically for DIYers and professional installers alike, this harness bridges the gap between your new stereo and your vehicle's dash architecture in seconds. This adapter takes the place of the standard wire harness packaged with your new receiver. It features a dedicated 20-pin BOSS connector on one end that plugs directly into the back of your radio, and a 20-pin iDatalink Maestro connector on the other end that locks seamlessly into a compatible, vehicle-specific Maestro T-harness. By removing the need to splice or solder wires, it guarantees a clean installation while preventing common wiring mistakes that can lead to blown fuses or audio dropouts.
