I had the same problem hearing my turn signal clicker after changing out my radio. Added some wire to the clicker and moved it up to right behind the instrument cluster. I hear it easily now.It's been a while so I'm trying to remember. I know the first harness I followed the instructions to a tee, but still ended up with a battery drain. IIRC on the replacement harness I don't think I did cut it as I was trying to see if something I did caused the drain and wanted to rule everything out. Since I had no issues, I don't remember going back and cutting that wire later though. I do need to go back and open up the dash and rearrange some wires though since I have an annoying rattle back there since the install. Maybe this is a good excuse to do so this weekend and then I can confirm what I did. My only complaint so far now that I'm a few months in is since the harness uses an audible relay to create the turn signal sound vs through the speakers it's difficult to hear the turn signal clicking while driving as that relay is tucked away in the dash. It's a minor problem I know, but I find myself double checking if my blinker is on sometimes since I don't hear the audible feedback like I am used to.
