My D3 arrives on tuesday and i just need to be clear on the PB wire grounding. There are 2 wires connected to the parking brake switch according to the install manual on line. Which one of these do i ground and do i need to cut the switch off in order to do this properly?

thanks

Waiting for my D3 like most, but have one stupid question. When I do the bypass can I ground the mute and the parking wire to the ground wire in the harness?

yes
