Head Unit Connection: The HRN-HRR-GM5 supports iDatalink's Direct T-Harnesses (sold separately) for direct connection to select iDatalink Serial Port compatible head units (including Kenwood, JVC, Alpine, Sony, and Pioneer radios) - replacing the wiring harness that comes with your aftermarket stereo (some hardwiring may still be required). If connecting to an aftermarket head unit that does not support an iDatalink Direct T-Harness, you'll need to cut off and remove the 20-pin black connector from the HRN-HRR-GM5 harness and splice each wire directly to the aftermarket radio's corresponding wire..
