It's a little scary to do --- the headliner needs to be released from the perimeter. At the very corner pinch the headliner tightly and gently pull it down and away from the corner - it only has to move a little bit to get released. Once one area is cleared of the "ridge" it can get worked around easily. You only have to pull it a few inches around to expose the harness. That's the easy part. The trim panel on the hatch needs to come off and you may need to remove the hinge altogether. The harness should get replaced (don't know if they're still available)---or you can trim the upper end see if you can get enough "virgin" harness through the hinge and then redo the upper connections -- or you can fudge it altogether and avoid future grief by running the wires through the headliner. I'm not so fussy and did it that way on my '93 245. The external "loop" needn't be very long and never interferes with opening/closing or loading cargo. - Dave
