What does the white wire clip to?

gr, please don't try to post those like that. Instead, put a link so they can download the full size one

You can get them from Mymopar as well as a few shop (factory) manuals

Wiring diagrams........

And the link to the two

http://www.mymopar.com/downloads/1967/67DartB.jpg

However these ARE NOT Mopar original and are not always complete or accurate

The factory shop manuals are almost always better

And some from our own site, somewhat of a mixture of the above:
