Got a new deck! Help needed with stereo harness wiring

[tapanpatel88]

Hey guys. I just bought a new double din JVC deck and I needed some help with wiring to the stock harness. I have ordered a Scosche TA02B wire harness as you can see from the following pic:



Yellow -- 12V Constant
Red -- 12V Accessory
Black - Ground
Orange -- Dash Light Dimmer/Illumination
Green -- Left Rear Speaker (+)
Green with Black Stripe Left Rear Speaker (-)
White -- Left Front Speaker (+)
White with Black Stripe -- Left Front Speaker (-)
Purple -- Right Rear Speaker (+)
Purple with Black Stripe -- Right Rear Speaker (-)
Gray -- Right Front Speaker (+)
Gray with Black Stripe -- Right Front Speaker (-)
Blue - Power Antenna


I noticed that Scosche has a blue wire (power antenna) and the JVC harness ALSO has a blue wire (labelled: remote output wire). According to JVC, their blue wire is for output to an amp, equalizer, and power antenna.

MY QUESTION: Do I connect the Scosche blue wire to the JVC blue wire OR do I not worry about the two blue wires at all? Since our 2009+ Corollas don't have power antennas, I am guessing we don't connect the two blue wires at all. I just don't want to connect unnecessary things and risk damaging components!!!

Thank you!

This is the correct answer. Enjoy your new HU. Can't wait to see pics!

you don't need to connect it. just zip tie it or use electrical tape to secure it to the other wires so you have a clean install.

if you do manage to connect the two wires, it wouldnt matter since there's no pin and wire connected to it once you hit the factory radio wiring.
