Hate to say it and I do hope it doesn't come to this but you are probably going to have to buy new sensors. They are very finicky and its always a toss up when they're extended.. seen them die for much less. I always recommend to install them in the upper bungs (if your headers have them) to avoid extending the wiring.I cut the harness wires and didn't mark them. The harness end got thrown away so I had to get an aftermarket electrical connector. I did solder the wire connections but I don't know what color wires are for the o2 heater wires and what color wires are for the sensor. I.e black sensor wire connects to orange harness wire. White sensor wire connects to blue harnes wire.
