I went to replace my head unit today, and when I took the factory one out, some of the wires got hung up and pulled out of the harness, and was unfixable. I proceeded to snip off the factory harness, and just hardwire. I'm having some problems though. First question, I see there are two plugs that go into the factory deck. What do they both do? I'm confused as to which ones are speaker wire. I found the ground and power, but still need speakers and constant power. Any help will be greatly appreciated.
