The Torch Control Box should be placed in the trunk of the car within 3-feet of the coil packs. It should be placed in an area where it will not be covered, hit or agitated by everyday items stored in the trunk. The suggested place for placement of the Torch Control Box is in an open area where the spare tire is stored. DO NOT place it outside of the car as it could be damaged from water, excessive heat and/or road debris.
