Hi and welcome to JustAnswer,

Thank you for the question and your patience. Should you still need assistance for information purposes only...

Initially, the simplest approach would be to hardwire directly the Kenwood's:

  • • yellow wire to an always available +12 source;
  • • red wire to a switched +12; and
  • • the black wire to the vehicle's chassis/metal ground and not only to the harness' ground line.
