Default Primary wire on distributor

Hello, sorry to be bombing all this week with questions. I am starting to connect all the wires up on my engine. The distributor has a large black 1/8th inch 2 feet long wire coming out of the side. When I look at wire diagram in the service manual, it just says Primary, and does not show it going to anything.
This is the only wire that has me stumped. Thanks

'55 wiring diagram from the Service Manual on Safari Larry's web site here https://www.pontiacsafari.com/55/Sho...nstruments.pdf
shows that wire connected to the - terminal on the coil.

Does this work for the 57 too? Thanks

Thank,s after reading further into the service manual I figured it out. What had me wrapped around the axle was the extremely long length of the wire. At first I was thinking it attached to the starter solenoid, but that made no sense, and the wire diagram did not reflect that either. Thanks Bill.
