Default Bypass CCM/ALDL

Has anyone bypassed the CCM via the ALDL connector to read data, I already know how to silence the CCM but would like to bypass altogether,
Thanks In Advance

Just seeing if it could be by passed, I sometimes like to use aldldroid instead of tunerpro
and since I got my new phone I have not been able to silence the ccm using aldldroid
on my phone. It's no problem I can just keep using tunerpro.

Are you using the ADX from TunerPro on ALDLDroid? That is what I do with no issues

Instead of cutting the wires as suggested above, the Tan serial Data wire can be removed from the ALDL terminal and reinstalled as needed.
