Part # EDL-312Replacement 9 curve ignition module box for ignition systems EDL-IGNS and EDL-BOIGNS. If you would like to UPGRADE from the stock 3 curve module to this 9 curve module, select the product option at the time of purchasing the main system. Then the 3 curve module will be removed and replaced with the 9 curve module so you receive only one module and are charged accordingly and correctly at checkout. If you already have the 3 curve module, it can not be taken in exchange for the 9 curve module because it is considered a sold item and used regardless if electricity has been applied to it.
