Ryan,
You have it all hooked up right...
The 10 pin white connector is your power feed...usually theres a T in there were you can connect it inline incase you don't have an extra spot on the bottom of the box.....Then theres the connector for your candle which is the 4 pin molex plug.
You say that your chaser lights don't come on....do the LED lights come on at all? I would take the topper apart and make sure the connections are good..And remember, some toppers don't have the chaser lights....they are just on or off.
As for the one pin, i have this also, and its not connected to anything.
Hope this helps you alittle bit!
Tom
