My Alpine CDA-105 is starting to kick the bucket I believe. Symptoms are full power on/off sporadically and I have to manually turn if on/off when I turn the vehicle on/off.
My question is will a new Alpine CDE-121 plug right into the Alpine harness alright in the vehicle with the CDA-105 or will I have to wire in the new harness for the new radio? I think the harness that is in there now is hardwired.
Thanks in advance for any help.

The plugs are not the same.

FYI - I now use the Euro (DIN?) standard for my interfacing. (2 rectangular 8-pin plug/sockets; a 3rd for extra features.)
I got sick of rejigging each HU to whatever wiring I had - at least now I merely wire the HU to the DIN.
[There are pre-wired commercial adapters, but being a cheapskate, I make my own.]
And rollbacks are a breeze. After trying 2 other (cheap) HUs, I'm going back to Alpine!
