You need to get the 1st, 2nd, and 4th lights (from the left) lit together to get the map piece.
Turn the lights on in this order : 4th, 2nd, 1st. The map piece appears under the drapes near the 3rd light.
The archway is right to the right of the trading post in the golden harbor. You need to turn the lights on and off according to the combination.
In Golden Harbor, turn on the 5th, 3rd, 4th, 2nd, and 1st lights in that order. This will prevent you from turning the wrong ones off.
The arches are the curved doorways at Golden Harbor. When you light the street lights there (4th, then 2nd, then 1st), the map piece appears at the top of the third arch.
I'm pretty sure you turn the lights on a certain way.... Theres more info on that when you type 'How do you beat skullduggery island?'..... I personally haven't been on in a while. Hope this helps!
There are five metal street lights or lamps along Golden Harbor, from the dock (1st) to the right side of the bank (5th). To recover the map piece, you have to turn on the 1st, 2nd and 4th lights. They should be turned on in the order 4-2-1 or 2-4-1. The map piece appears in the draped doorway.

The lights at Golden Harbor have to be turned on in certain sequences, or some go back off again. You need the 1st, 2nd, and 4th to be lit. The sequence of lighting them can be 4-2-1 or 2-4-1 (this may have changed since the island was opened).
You have to turn on all three lights : 1st, 2nd, and 4th. Turn the 1st one on after the others are on. If it is on when you turn on the 2nd one, it goes off. So turn them on 4, then 2, then 1. The map piece appears in the draped doorway.
At Golden Harbor, the street lights are used to recover the piece of the Treasure Map. Turning on some lights turns others off, and you need the 1st, 2nd, and 4th lights to remain on. Turn on the lights in this order (counting from the left) : 5th, 3rd, 4th, 2nd, 1st. The map piece appears in a draped doorway near the 3rd light.
Because turning on the 2nd light (from left) would turn off the 1st one, light the 4th, then the 2nd, then the 1st. The map piece appears in the draped doorway near the 3rd light. You do not have to touch the 5th or 3rd lights. The series 2-4-1 also works.
it has something to do with the lights
You have to turn on all three lamps: number 1, 2, and 4. But turning on number 2 turns off number 1. So turn them on in the order 4, 2, 1 or 2, 4, 1 and the map piece will appear in the doorway with the drape.
