[Healeys] BN7 Battery Cut Off Switch

[Ronald J. Ray]

I'm posting this question for a friend in our local club.

Page 131 of the Anderson/Moment book shows the location of the battery
cut-off switch in a BN7.  
How are the ground wires and coil wire routed?
Where does the ground wire from the switch to ground connect to the car?

Thanks.
Ron
