Hello again. While tinkering around the bike I have noticed a badly chaffed o2 wire, after where it plugs into from the actual sensor plug. If that makes sense? Basically buying a new sensor won't help because that side is good, it's the wires after the plug that are damaged. Looks like this wire gets wrapped into a larger bundle of wires that i assume goes to the ECM?
How do I go about fixing this?
