freebeard,
Sorry, I forgot to ask about the crossbar.
I did ask if the other Toyota connectors, such as the Prius, would work. Sorry, no luck there.
It may be possible to break that big harness into smaller, usable bits. For example, it might function well as a battery>controller as well as the controller>motor harness. I think it's all of the high power stuff for the Highlander.
