2010 Mazda 3 Remote wire Stock radio

My system should be ready to install tomorrow. I ordered a LOC unit to run on the back of my STOCK radio, my amp kit should be here in the morning as well and I got my box built and carpeted. I just now thought about it.. Where do I wire my remote wire to on a stock radio? I don't want to tap into any fuses.

Your remote wire should be a blue wire in the stock stereo harness. Often times in most cars it is the blue and white wire.
I drive a Mazda 2 and it was blue and white.

My 07 Speed 3 was also blue and white on the stock stereo harness
