Reddit reviews Posi-Lock Connectors 14-16 gauge #601 Pack of 9

Get on Crutchfield, they'll sell you what you need all in one package for a competitive price.

As for wiring the harness, sorry to say but it's very rare to find a pre-made double ended harness. Blaupunkt used to offer those for "select cars" a decade ago, but stopped because not enough takers.

If you're not comfortable with soldering and hate crimp connectors, you have two other options that are pretty good:

First there's these things...

They kick a lot of ass, literally solder and heat shrink in one step with a cig lighter or heat gun. I wouldn't use them under the hood (too hot under there) but in the dash? Awesome!

Other option is these things:

Those things will join wires with no tools at all, apart from strippers of course.


These are fantastic btw, if you think you'll ever strip another wire in your life later https://www.amazon.com/Neiko-01924A-Ultimate-Self-Adjusting-Stripper/dp/B000IYTCG6/ref=sr_1_9?s=hi&ie=UTF8&qid=1486599547&sr=1-9&keywords=wire+stripper

Posi-locks should work too, easier than soldering
