This wire harness provides a line out converter for connection to one set of RCA cables to provide an audio signal to an external amplifier. Also pre-installed on the harness is a remote amplifier turn on wire. This wire, along with a set of RCA cables, is run to your aftermarket amplifier. All that’s left for you to do is connect your own main power wire from your battery and a ground.
Converter adjustment instructions:
- After completing all of the necessary connections, turn the adjustment pots all of the way down by rotating them completely counter-clockwise.
- Turn the stereo system on and adjust the main volume control on the stereo to approximately 3/4 maximum volume.
- Select one of the adjustment pots and turn it slowly clockwise until you notice audio distortion and then stop.
- Turn the remaining pot to the same position as the previously adjusted pot.
Compatibility Notes:
- Audio volume to the amplifier can be adjusted by the dials on the harness. For easier access we recommend using an external volume knob.(Not included but we can provide one) - If this is being installed on a vehicle with a "premium sound" system such as JBL, this harness may need to be connected at the JBL amp and not directly at the radio. - A variety of wire colors may be used for the remote wire coming off the harness. Regardless of color, rest assured it is for the remote turn on of an amplifier.

I had my system all installed and the remote wire gives no signal. And when radio doesn't control volume going to amp. Radio volume is off and the subwoofer is still pounding. Don't recommend.

Wasn't expecting this RCA adapter to work with my 2014 Prius V Five but it did work pretty well. It should work with other 3rd gen Prius if you are wondering.

Works great on my 2017 Toyota Tundra crew max, with JBl. However, I had to cut the remote wire and move it to the rear harness, on top 1 slot, light blue wire.

Plug and Play like it says. Real simple. It may be a little tight when putting your deck back in. But other than that. Works fine. Been in my Tacoma for about a month now and no problems.

It did not work for my 2016 Toyota Camry SE even though he claimed it would don’t waste your money on this. The quality looked OK but it did not work. Could not get no signal out of it the RCA leads.

Plug and play. Couple things to know. Audio adjustment is backwards, counter clockwise increases level output of the attenuator. Also, this splices into the front speakers. While I got this for a band-aid until I get a proper head unit that integrates into the iDataLink Maestro, this may be a large issue with others. If you only plan on adding a subwoofer to a stock head unit, you will also want a adjustment added either on the amp in side or amp output (a subwoofer volume controller). Currently, without pulling the head unit forward, the only way to adjust subwoofer levels are on the amp itself through it's interface, speaker balance (rearwards reduces subwoofer), or removing bass in the basic equalizer all together. Listening to a wide range of music from Rock to EDM...that makes it challenging.However, very easy plug and play and does work. Just a few limitations due to the stock head unit not being designed for a subwoofer. I do wish it had spliced into the rear speakers which wouldn't sound so weird when you shift sound output to tame the subwoofer. If you are running a smaller subwoofer, probably won't be an issue. Mine is way too powerful for the stock speakers to keep up with but the stock unit and speakers are temporary and no big deal.
