Take it easy buddy, I was asking how the signal travels because i didn't know.
Thank you very much for the info, it will be extremely helpful.

Based on what you said i can make a plug and play harness no problem that will work, but DSP will be lost.

Or a harness that retains the DSP but might have some issues with noise pick up.

Im going to start to do the DSP bypass one first and get back to you.
