This harness is plug and play once you wire everything up.
I soldered all the wires together and shrink wrapped them. I then used Tesa tape to clean up the wires. I used this harness with a Pioneer AVH-1400NEX in a 2009 Chevrolet Suburban.
Once installed, I didn’t even need to map the SWC. The SWC worked as advertised, with one exception; the “next” button would work.
You don’t need any other item for this to work. I highly recommend it!!
