I spent part of this afternoon, unhooking two crossovers driver/passenger side also an amp. All work, but there was major noise interference possibly. Had my battery tested at autozone, it checked out good but was at 80% due to the amp (unwanted stuff)I mentioned.


After the removal I notice this ubhooked blue plug next to the kickpanel fusebox.

What is this plug for?


Then I spotted this white plug below the obd2 plug. What is this plug and found another white one in between the steering wheel(could this be the horn plug) not pictured.
