what you need to make it perfect without cutting or splicing any wire is:
-electric divide harness

-audio head unit T-harness (you'll need a male and female plug of the head unit) and make sure that all pins is populated (I ordered two of each cause this one have one pin missing)

-4 pin male plug that you can plug it with this female plug ( you can just use two wires with pins from the divide harness cause you don't need them all )

and most of all is that you need the 16-pin and the audio 20-pin harness
