I have inherited a 1999 Carrera convertible. It was left outside to rot for the last three years and I am learning about the car from scratch. Have lots of experience with older American cars and one 94 BMW. First problem out of the gate is the wires leading to the O2 connector have been eaten thru by mice. I am looking for suggestions as to where I can find a pick your parts type place and cut off the wire bundles for splicing into this car. Is there a better way?
