Not sure.Were the missing connector housings not available from Toyota? The main reason I don't buy them there is that Toyota only sells bare housings; I can get housings, terminals and seals from Ballenger, most times without having to hunt for them. And, AFAIK, Toyota doesn't sell terminals or seals.
Partsouq had some not many. Might put in an inquiry with my local dealer, see what they can do
