aftermarket radio main harness to the JGC1 T-harness and

connector of your JGC1 T-harness.

connector of your JGC1 T-harness.
If the vehicle DOES have a factory amplifier:

connector of your JGC1 T-harness.
• Plug the female WHITE connector to the male GREEN
connector of your JGC1 T-harness.
STEP 3
