insert .02. Just went out to my beloved VX to check this out. Something else you might think about doing is this. (Did you read my thread awhile back about the door handle repair? There is a reference to a 'Bone Tool' sold by ipdusa dot com, 5 bucks, but it you happen to have some hard plastic laying around you could make one). Anyway, using the bone tool, you could work the cable into the the leading edge of the head liner then run the cable down under the rubber seal between the A-pillar and door right down to the side of the dash and underneath to the OBD plug. This might be a way to prevent breaking anything in the A pillar cover. When I installed the map lights in place of the useless rear view mirror, I was able to pull the headliner leading edge down to feed the mirror map light wiring thru to the aircraft style lights that I installed. Pictures are in my gallery. Just another thought Bart.
Greetings, Earthling. We come in peace... Never mind "Paris to Dakar", the VehiCROSS looks ready for the Martian desert.
