'49 Coil Wires - 8BA

[George49Ford]

Rookie question here. I just put in replacement distributor and coil (not new). Coil terminals are marked + and -. I made an assumption that + is the "hotwire" from ignition and - goes to the distributor. I can't find it in my (well worn) Green Book, and all my wiring diagrams don't specify which is which. Haven't tried to start it yet, but did I get the wires right, or possibly, does even make any difference. Thank You for all replies.
