Richard, since you've done it, perhaps you could enlighten me on one point. The instructions say to "remove the rubber grommet behind the taillight assemblies." I found the grommet in question, but I can't get my hand in there and the opening doesn't appear big enough to get the connectors through anyway.
How on earth did you manage it? I don't suppose there's any chance of you posting a photo?
Update 12/26/11: well, I found I could get to it from behind the bulkhead, i.e. from underneath the vehicle. However, all that is moot because I discovered that there is no opening at all behind the right taillight at all, just blank metal!
So, sadly, this kit doesn't work at all on my van. Clearly, not all TCs are made the same. Check yours before you buy.
Cheers,
Lewie.
