The following (3) wires are for the aftermarket radios that have navigation built in:
• Connect the Green/Purple wire to the reverse wire (if applicable).
• Connect the Light Green wire to the parking brake wire (if applicable).
• Connect the Blue/Pink wire to the speed sense (V.S.S) wire (if applicable).
From the BX-GM5 harness:
(a) 30-pin harness to the aftermarket radio:
• Connect the Black wire to the ground wire.
• Connect the Yellow wire to the battery wire.
• Connect the RCA jacks to the audio AUX-IN jack (if so equipped).
Note: This will only be required if you care to retain either factory AUX-IN,
rear seat entertainment, or satellite radio.
Digital amplified vehicles:
• Tape off and disregard the Green, Green/Black, Purple, Purple/Black wires, they will
not be used in this application.
• Leave connected the two 4-pin connectors located between the 30-pin and 22-pin
connectors.
Note: The resistor pad harness will not be used in this application.
