Al --
Please read the whole rule. The intent is that the connector provided in the kit is the connector that must be used. This is not an error.
"<R20>
The 12v battery must be wired directly to a quick connect / disconnect connector (provided in the kit)"
As you can see, the rule clearly states that the connector is provided in the kit. The reason that the word "a" was used, is that there are two of the connectors provided (the entire connector is made up of two mirror-image halves).
Sorry to hear that all your previous equipment uses a different connector - but for 2004 the rule has changed.
