If you install an aftermarket stereo you need this to retain factory antenna. It does its job.

I connected the blue antenna amplifier wire to my remote turn on wire coming from my head unit. Antenna function is perfect. I recommend using insulated butt connectors to connect wires together as this will eliminate any unwanted voltage drops in the system. This harness fit perfectly and allowed for the use of my factory window antenna. No complaints, thank you Metra for supplying the necessary wiring harnesses to consumers at excellent prices.
