Sorry I dont call people dont want to get my phone number out there. But I will do my best to help you on here iam not a big fan of typing myself. So the wires going to your speed sensor are damaged or there good?If there good your best bet would be to move the power wires to the radio or get some shielded wrap for the speed sensor wires. When I worked at saturn we used it for emi affected wires.
