As of the latest version The Grand Design can no longer highlight wires or let you disable any traps you find until Golem has been defeated. You cannot remove any traps other than the wooden spikes without a Picksaw or a better pickaxe.

While the explosion-proof Lihzahrd Bricks and the Lihzahrd Altar can only be mined with a Picksaw, most other objects in the Temple, including traps, can be removed with low-tier tools.They pose a very high threat to players without late-game equipment. Even before entering Hardmode, Lihzahrds and Flying Snakes can spawn outside the temple, if the player is standing directly in front of a Lihzahrd Brick Wall (in the Temple's entrance, for example). Dungeon (Otherworldly) (Otherworldly).mp3.As in the Dungeon, all Temple traps, pressure plates, and wires can be looted by the player for use in player-built mechanisms. They are activated by Lihzahrd Pressure Plates, which only respond to players (enemies walk on them freely without triggering them). Traps occur much more frequently in the Temple than in the Dungeon and are far more damaging. The entire Temple is filled with several types of traps, including Flame, Spear, Spiked Ball, and Super Dart Traps. Several Power Cells are found in the Temple's Lihzahrd Chests and are dropped randomly by the Temple's Lihzahrd and Flying Snake enemies. The Altar can be used to summon Golem at the cost of one Lihzahrd Power Cell. The Temple's entrance leads to a long corridor that winds downward through several chambers, ending in a large room at the bottom containing the Lihzahrd Altar. There are, however, several methods to enter the temple prior to defeating Plantera. It is generally not possible to enter the Temple via any other conventional means since Lihzahrd Bricks can only be mined with at least the Picksaw dropped by Golem, and Lihzahrd Brick Walls impose numerous restrictions, e.g. Unlocking the door consumes one Temple Key from the player's inventory, and the door remains permanently unlocked for all players in the world. The door is initially locked, requiring a Temple Key to open, which is dropped by Plantera. The Temple is entered via the Lihzahrd Door located at one of its two top corners. Defeating Golem triggers the spawning of Cultists, used to summon the Lunar Events. The Lihzahrd Altar found in the Temple's final chamber is used to summon the Golem boss. The Lihzahrd Furnace, a crafting station for further Lihzahrd-themed furniture, can be found in its Chests. The Jungle Temple contains unique Lihzahrd-themed enemies, traps, and furniture. It is always present in any generate world, but can only be properly entered after Plantera has been defeated. The Jungle Temple (also known as the Lihzahrd Temple) is an enclosed structure constructed of Lihzahrd Bricks and located in the Underground Jungle.
