None that I know of. Paul up in Canada and Greg in OKC have made a lot of videos on the car, but not that one. And, sadly, the poor text description given by Wayne (Shamrock) in that link above is all there is.
Our cars' documentation is really pretty poor. I'd sure go along with verifying the voltage change at the module in the trunk, if you see it change when the D ring is turned, you need not get in there and screw with it anyway. And I gotta tell ya, in the 12 years Iv'e been on here, MOST of the time that switch was suspected, turned out to be no power to the module OR a water damaged module.
