My '94 90TLRS has a nick in the insulation of the harness between the engine and the control box. The nick exposed a yellow wire which lost a shaving of its insulation and exposed a tiny spot of bare wire. Does anyone out there know what this yellow wire is? I put some 5200 on it to seal it up for now. If this is a low current application, I'd like to just replace the one compromised wire rather than buying an entire harness.
