ADVANCE AUTO WIRING HELP

[mgbv81970]

I'm in the middle of installing an Advance Auto Wire harness in my car.  I have a question regarding the windshield wiper harness.  On the Advance schematic it's showing the green wire (ignition hot) going to both the green wire on the wiper switch as well as the BLACK wire on the wiper switch.  The Bentley manual shows the black wire being grounded.  I'm confused.  Anyone install one of these recently that can help me out here?  

Thanks,

Scott

There is an on-line standard wiring schematic for a 1970 MGB on the Advance Auto Wire web site.

Scott, if I recall, the wiper motor gets a hot wire that's not switched.  Then, it gets a ground & a second ground that's switched.  The switch completes the circuit; motor runs.  Turn switch off & the other ground completes the circuit for the wipers to park.  Don't have the diagrams in front of me so going off memory & can't quote the colors but that's what I recall from the diagrams on the advance auto wire web site.
