Rewiring/Coil Question

[MikeAH100M]

Installing a new wiring harness in my 100. The connections to the coil are marked as SW and CB on the BN2 wiring diagram but the newer coil in the car is marked as "+" and "-". So which is SW and which is CB? The CB terminal continues to the Distributor. SW to the ignition switch and the fuse box. The car has been converted to negative ground. I'm sure the answer is simple but this one plumb evades me.

+ = sw
- = cb

Also rewiring 100-4, positive ground. Does that mean += cb and -= sw?

If your battery positive post is the hot one going into the cars solenoid, the the + on the coil is connected to the ignition switch. ( this would be a negative ground system, used on most modern cars )

If you battery negative post is the one going into the cars solenoind, the - on the coil is connected to the ignition switch. ( this would be a Positive ground system, as found on many early English cars ).
