ASD bypass harness takes the ASD module inputs/OEM HU outputs and bypass them into the Base Stereo speakers/HK(674) OEM amp inputs. Therefore, no ASD engine sound outputs are mixed with the OEM audio system. ASD module is still operational and visible to the dealer computer so all OEM car software updates can be performed without ASD errors.
New harness design -no longer requires disassembly for installation. Full 100% PnP.
