I thought Behr only made units for models where a/c was offered as a factory option, i.e., w100, w108/109, w111. These I’ve seen trimmed in various interior colors.
For w113, which were never available with factory installed a/c, I thought Kuhlmeister and FrigiKing were the dealer installed units? To the best of my knowledge, these were always trimmed in black. I have, however, seen them re-trimmed in matching colors when owners have “refreshed” their interiors.
