Help Please ! Wiring Diagram
2015 Corolla S (Plus?)
I was attempting to install a power wire for an amplifier and i accidental cut the insulation on a wire in the wiring harness that passes through the large boot on the passenger side. The wiring harness must have rubbed against a burr on the sheet metal of the car's firewall.
I had the dealer check everything and the only thing they found wrong was this wire, which they completely cut before deciding they did NOT want to fix it. They told me the only option was to replace the entire wiring harness or find somewhere else that could run a new set of wires alongside the existing ones (but that they would not do this second option themselves).
The wires are a twisted pair (black/white wires) that are part of this harness. It has affected the main computer (i have no power steering or traction control and the RPM gauge, daytime running lights, oil temperature gauge are all not working at all).
I cannot find a wiring diagram anywhere, does someone have a wiring diagram of this harness so i can tell where these wires go?
Or have any recommendations? The Toyota dealer said they had a car come in with a similar problem and they attempted to repair by soldering the wires, but the car ended up having problems with the computer all the time. The car only has 5,000 miles on it, i can't believe something so small is turning into such a big problem.
