Does anyone have the directions for installing the MSD BTM part #8762. on the side there is the inlet for the small air line and then there is an adjustment next to that which says START POINT and it can be set from 0-5. Then there is the dail which goes into the vehicle can be set from 0-3. what do I set the start point on the box at. and how much on the dail. It also has a red, black, white and yellow wire. Thanks in adv advance for any help.
