itaste vv repair

[gingersnaps]

I was handed an itaste vv to see if hubby can fix it. there is a disconnected grey wire at the top that I assume goes on the board. but there are no leads anywhere to go to the p/n on the 510 connector. anyone have any pics for the connections from the top board to the connector or links to pics?

After more looking does the grey wire connect to the positive pin? If nothing is missing that's what looks like to me but would like to be sure.
