If your car is like 15 years old or newer, spend the extra money on a harness adapter. It was a walk in the park for my 2001 ram without the harness, it was a total nightmare for my friends 2008 Altima.
Heat shrink butt connectors are best to use, im installing my new jvc stereo and subwoofer with an amp and my exhaust cutout on my crown vic tomorrow night gonna be fun i love messing with wires
So my radio has 2 plugs besides the harness, a red one and i believe its grey or white, they look like maybe for an amp maybe, do i plug them in the radio also or leave them unplugged thanks
Mine also has a weird box with a fuse and 2inputs 2 outputs. The one who did this before I got the car messed up a lot of wiring and I dont know what is that little boxes purpose
And the times of this ignorance God winked at; but now commandeth all men every where to repent: (Acts 17:30) Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God. (James 4:4) Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it. (Matthew 7:13-14)
