I have a 2002 mercury sable and am changing out the factory to a pioneer head unit. I have a metra dash kit, and am able to change the heater and a/c controls with no problem.
My issue arises with the wiring of the speaker wires and antenna cable. I can directly wire the wiring kit that came with the dash kit to the corresponding wires on the back of the pioneer unit, however I do not know where to plug the connector into.
On this dash kit, there are two connectors, the first one connects to the factory connection, this works and the a/c controls work as well. The second connector is where I am having the problem. This connector is where the speaker wires and the antenna cable are plugged into, however I cannot find where this connector plugs into.
