I am new here, but I have been reading on the site for quite some time. I just got my D3, and I am getting it installed on monday. Best buy will do the installation.
My question is, would you ground the parking brake and the mute wires regardless of rather you are trying to do the bypass?
I ask because I do not know if best buy will bypass the unit or not due to legal ramifications. But if the wires are grounded regardless, then I can just move the wire myself and they can install it. So can someone tell me?
