First car ever, yaris and DIY upgrades

[2008sedan]

At 34yo, I finally bought my first car, 2008 Yaris sedan. I love it but I wanted to upgrades a bit of the aged components. Found a pioneer after market sph-da 120, and hooked a backup cam over the license plate. Im waiting for metra 95-8202to close the sides of stereo. I drilled a usb/aux in the dash and in the console between seats. I might do fog lights and new speakers, the stock one seems to make vibration/distortion noise at high levels. Does harness and connections always there in the bumper for fog lights?

Thanks and im glad i have found this forum!:headbang:

Is that an AUX jack remount? Like that as my stock 08 has always crackled out unless I hold pressure on the plug.
