CONNECT WIRES
- Connect wires below to the matching function of each wire on your receiver (refer to instructions supplied with the receiver).
- IMPORTANT: The wire colors of your new receiver may, or may not, match the wire colors of the adaptor. Match adaptor and receiver wires by function, disregarding color.
- Make final wiring connections following instructions on the next page.
Note: Not all Toyota pickups have factory-installed rear speaker wiring harnesses. If present, it will be taped to the power/front speaker harness.
Note: In 1998-2000 Lexus GS vehicles, these harnesses connect at the amplifier location behind the passenger’s side kick panel. The 12 Volts Constant power, chassis ground, and speaker wires must be lengthened in order to reach the kick panel area. The power antenna and 12 Volts Switched power leads must be spliced at the radio location.
Note: If the adaptor harness does not match the vehicle radio harness, the matching plug may be found below the factory radio at the amplifier. The amp must be bypassed by unplugging the matching plug from the factory amp and plugging it into the adaptor harness.
