PICKUP PLATE INSTALLATION Remove the existing trigger/points plate and rotor, points cam and advance. Refer to the bike’s Service Manual for the proper procedure. EVOLUTION AND LATE MODEL SHOVELHEAD V-TWINS 1. From inside the cam/ignition housing, feed the free end of the MSD pickup harness through the wire access port. Note: The harness includes a heat-resistant acrylic sleeve that fits snugly inside the port opening. Do not pull the sleeve completely through the port. It must be positioned to protect the wires as they pass through the port opening. 2. Mount the MSD pickup plate inside the housing (Figure 1). Note the “adjusting notch” on the edge of the plate. This notch must be located over the series of “steps” inside the housing (about the 7 o’clock position as you face the housing). One of the sensor units will be at approximately 12 o’clock. SPORTSTER MODELS 1. On Sportsters, the wire access port must be enlarged. Use a 9/32″ drill bit to enlarge the wire port. 2. Remove the wire harness clamp of the pickup assembly and route the wires through the port. 3. Mount the MSD pickup plate inside the housing (Figure 2). Note the “adjusting notch on the edge of the plate. This notch must be located over the “cast notch” inside the housing (about the 11 o’clock position as you face the housing). The shorter of the two sensors will be approximately in the 9 o’clock position. 4. Install the hold-down/standoff screws with flat washers until they are snug – do not tighten at this time (Figure 3). 3. Put the MSD rotor in place on the end of the camshaft. The locating pin in the rotor bore must align with the groove in the cam. Do not force the rotor on the camshaft! Push the rotor into place until it is tightly against the end of the cam then snug the retaining screw. 4. Check the distance from the outer surface of the pickup plate to the end of the installed rotor (Figure 4). If necessary, add shims until the measured rotor height is 9/16″ (+/- 1/32″). 5. When the rotor height has been verified, remove the retaining screw, place a drop of Red Loctite on the threads and reinstall the screw to the factory recommended torque
