    That looks like the harness or zip tie was digging into the pipe. Just a side note, the aluminum pipe has a foam wrap around it by the engine where it would rub against a side wall. I think that’s a sign nothing is to touch this pipe. I would check under the harness or zip tie even if you don’t see erosion.

    The harness was against the pipe with enough pressure for it not to move around.

    I checked mine today. It was totally fine but moved it just as a precaution.

    This is an old thread, but I have my grille off working on my transmission cooler install, so I decided to fix this issue while everything is apart.

    Disconnecting the @iHacker harness inside the cabin (dimming harness) is problematic because the terminal end was installed after the harness wire was pulled through the firewall grommet. I wasn't looking forward to depinning that terminal end under the dash and fishing that wire through the grommet again, so I came up with an alternate plan.

    The air dams on either side of the radiator are held in place by six push fasteners that can be easily removed by prying out the center pin. I removed the air dams on both sides, and loosened the fasteners holding the washer reservoir in position for working space. I then unplugged the passenger-side end of the @iHacker harness from the headlight. I found it was easier to simply remove the parking bulb from the headlight rather than work the connector. I cut the tie straps along the front grill area and AC tubing, then loosened the two nuts and raised the lower grille plate in order to remove and pull the harness end back across the front of the truck.

    I then pulled the harness end with the plugs and park bulb back through the radiator bulkhead into the battery area, and then routed the harness back to the grille area following the AC harness. The gray AC harness exits the engine compartment to the grille area under the bottom of the driver-side air dam. I taped the @iHacker harness to the AC harness at the push-in support that goes into the bottom of the air dam, then re-connected the harness at the passenger side headlight. I then distributed the harness across the grille area and re-installed new tie straps.

    It would probably have never been an issue with the ribbed conduit I installed, but I feel better for making the change. :thumbsup:
