iDatalink

This iDatalink HRN-DSP-GM3 harness connects a Rockford Fosgate DSR1 digital signal processor (sold separately) to your Chevy or GMC vehicle with no factory amp, so you can add digital signal processing as well as an aftermarket amp without losing important GM features and functions. This T-harness connects to the factory radio's harness, supplying audio and databus signals to the DSR1's Maestro interface without any wire splicing. This harness also provides connections to the factory speaker wiring, which you can conveniently use for your aftermarket amp's outputs.
