I am prepping my harness for install. The Kenwood side has a Park SW wire to control when and if you can watch DVD's and stuff. I read in many places that with the kenwood all that needs to be done is tap into the ground. Which is fine by me. Is this a correct way of doing it? What I did was grab the ground from the harness I bought to the ground from the kenwood harness and then throw in the Park SW (green) in and twist all three and then add butt connector. Or would the proper way be secure the two ground and then add another point in the cable add a quick splice.
Thanks for the help.
