I will be purchasing an Alpine CDA-9815 along with the changer CHA-S634. What other wires, harnesses, etc will I need to complete the installation? Thanks for the help!!

 

I just bought this unit myself, and I have the same changer. The only thing you will need is a wiring harness that way you will not have to cut any wires. Here is a picture of Lucid harness. He is a site sponsor and does a great job.



Also while you are there, if you want maintain your dash controls with your new unit he has a interface available to do that. Click Otherwise you should not need anything else to install, all other wiring should be included.

If you want to gain functions on your dash controls DJ Qube's Dash control unit is awesome. I have this and it works flawlessly with my 9815.
