Yes, you would want a 7-Way Molded Trailer Wire Connector # H20042. You will need to cut off the 9-way that is on your 1984 Holiday Rambler trailer and wire this connector on it by function. However, you should note that in going from the 9-way to the 7-way you will lose 2 circuits that will go to your trailer.

Since 9-ways are a thing of the past I do not have any wiring diagrams or typical wiring charts for the 9-way to help you wire up the # H20042.

I attached an FAQ article on trailer wiring for you to check out also.
