STEP 1 – BATTERY CONNECTION Locate the battery and disconnect the negative battery cable. Mount the module in the open area in front of the battery with 2-tie straps or velcro straps, directing the harness from the module towards the 6 o’clock position. STEP 2 – THROTTLE POSITION SENSOR (TPS): Remove the air cleaner assembly and unplug the TPS sensor connector at the TPS sensor. The harness includes (2) TPS connectors which should be routed under the gas tank into the factory wire loom to the TPS sensor. The TPS sensor is located on the left side of the throttle body. Plug the (2) TPS connectors from the module in between the TPS sensor and to the factory TPS connector. STEP 3 – O2 SENSOR: Systems equipped with factory O2 sensors Rear: Unplug the Rear O2 sensor connector from the factory harness, which is located at the Rear exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors and connect one connector to the Rear O2 sensor and connect the other connector to the main factory O2 sensor connector. Front: Unplug the Front O2 sensor connector from the factory harness, which is located at the Front exhaust pipe. Route the module’s harness which includes (2) O2 sensor connectors, and connect one connector to the Front O2 sensor and connect the other connector to the main factory O2 sensor connector. Systems not equipped with factory O2 sensors NOTE: Many aftermarket exhaust systems are now equipped with plugged O2 sensor bungs which can be removed to accept an aftermarket O2 sensor. Typically these bungs already have a thread size of 18 mm x 1.5 mm. Exhaust systems not equipped with O2 sensor bungs need to have the supplied 18 mm x 1.5 mm thread size bung welded to the exhaust pipe in order to install an O2 sensor. The O2 sensor bung should be installed 3 to 6 inches away from the rear cylinder exhaust port and in front of the exhaust torque tube pipe area. The module prefers to receive information from the O2 sensor from an area that is NOT contaminated from atmospheric air. This air may enter through the tail pipe of an unrestricted or un-baffled exhaust pipe. The bung should not be installed in the “5 to 7 o’clock” area. If mounted in this area the O2 sensor can be damaged. The moisture from the gases exiting from the rear cylinder exhaust port will harm the ceramic shell element of the O2 sensor.

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

Remove the 4 bolts that hold the exhaust cam cap in place, lift the cam cap off. It may be necessary to pry very lightly on the cap to lift it off its dowel pins. Do not use the cam lobes as the pry point. Be careful not to drop the dowels and also be careful to not lose the half moon shaped retainer for the bearing under the cam cap. Remove the 6 bolts that hold the intake camshaft cap and lift the cam cap off the camshaft, again, be careful to not drop the retainer or dowels. Lift the intake camshaft out of its pocket in the cylinder head casting. Remove the cam chain from the sprocket, set the stock camshaft aside. Lift the exhaust cam out of its pocket in the cylinder head casting and remove the chain from the sprocket. Do not drop the cam chain, dangle it over the side of the engine while keeping slight upward pressure on the chain to maintain its position on the drive sprocket on the crankshaft. Fit the half moon shaped retainers in the grooves of the Hot Cams camshaft bearings to ensure good fit, set retainers aside for the time. Using assembly lube, lube the shim buckets, bearing surfaces for the camshafts in the cylinder head, and pack some in the camshaft bearings. Set the exhaust cam into the cylinder head casting while at the same time fitting the cam chain over the sprocket. Make sure that you keep all the cam chain slack to the back of the engine. The cam chain pulls the camshaft sprockets in a counter clockwise direction and the slack of the chain must be kept on the cam chain tensioner side of the engine. The exhaust cam has two timing marks on it. When correctly installed one mark will be at the 9 o’clock position and the other mark will be at the 12 o’clock position. When correctly timed the mark at 9 o’clock will be aligned with the valve cover gasket surface. Repeat the above process for the intake camshaft. Again, make sure you keep the chain slack to the cam chain tensioner side of the engine. Check to be sure the crankshaft is still at TDC. The intake cam has two timing marks also. One at 12 o’clock and the other at 3 o’clock. When both cams are installed correctly, the valve cover gasket surface will form a straight line through the exhaust timing mark at 9 o’clock and the intake timing mark at 3 o’clock
