Replaced my front axle lock actuator harness today due to knocksnin the insulation. Have been getting random service 4wd lights. Took it to dealer last year and they said the wiring was damaged and quoted me a $400+ repair. This was only damage I found. Took my 6 months to finally look up the harness and order it. FWIW, it's a $25 harness. And took less than 5 minutes to replace. There's a guy on YouTube that sells a "repair" kit for the connector that he charges $30 for, where you cut the damaged portion of wire of and crimp new pins on.
There was absolutely zero oil inside the connector from oil changes.
Not sure if this will fix my issue. I think my actuator may be part of issue as well, because the part of actuator the connector is on wiggles. At some point, probably during one of my off-road excursion, something must have gotten past the Vice Design front skid plate and hit the actuator by the connector.
