How to complete Tumba De Las Esposa?
The ancient statue's head is in the center of the location. The lever is in the ruins on the left of the head. Activate it with the Retractor to make the head start rolling.
The head must fall into the hole presented in the picture above. However, activating the lever isn't enough. The head will get stuck in the ruins - you need to take it out of there. Use the Retractor - attach the beginning of the hook to the head, attach the end of it to somewhere near the hole. After a few tries, the head will move and fall down.
Follow the head by jumping down. The item will get stuck again - use the Retractor and direct the head accordingly to the water stream. Do that and the head will reach the circle. This opens the temple. Activate the light to complete the tomb.
