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.

1. Turn off the ignition switch before proceeding. 2. Select a convenient mounting location for the Bosch sensor. In general, the sensor should be mounted as close to the exhaust valve or exhaust manifold as practical. When choosing a mounting location, allow several inches clearance for the sensor wire harness. The wire harness must exit straight out from the sensor. Do not loop the harness back onto the sensor body. The sensor responds to oxygen pressure. Excessive backpressure will cause a reading error. For turbocharged applications, you must mount the sensor downstream of the turbo. 3. For temporary use during dyno tuning, you can mount the Bosch wide-band sensor in place of one of the original equipment rear oxygen sensors (after the catalytic converter). You can also use a sniffer in the tailpipe. For permanent mounting, an 18 x 1.5 mm weld nut must be welded onto the exhaust pipe. After welding, run an 18 x 1.5 mm tap through the threads. Failure to clean the threads may result in sensor damage. Note that most automotive muffler shops are familiar with oxygen sensor weld nut installation on custom pipes. Do not install the sensor until after the free air calibration procedure described in the following section. Always use an anti-seize lubricant such as Permatex 133A on the sensor threads. 4. Install the WEGO II unit. The WEGO II unit should be mounted where the LCD display will be visible during testing. You can secure the WEGO II unit with Velcro tape strips. 5. Connect the Bosch sensor to the 6 pin mating connector on the WEGO II wire harness. 6. Refer to Figure 1. Connect the black WEGO II wire to frame ground using the supplied ring terminal. Try to use an existing wire harness ground location. Do not extend the WEGO II ground wire or ground the WEGO II to the battery minus terminal or to the engine. 7. Connect the red WEGO II wire to switched +12 volt power. You can usually find switched +12V power at an accessory fuse on the fuse block. You can use the supplied fuse tap and 3/16″ female crimp terminal for this purpose

Remove the stock fuel induction system, including the manifold and disconnecting all wire connections. It is up to the technician as to whether the gas tank should be removed or just raised up in the rear. Picture 1 2- You will need to disassemble the stock induction system to remove the pre-listed parts for re-use. 3- Verify the new manifold size is appropriate for your motorcycle by sliding it in place. Picture 2 Picture 3 4 5- Slide the MAP sensor in place, being sure not to pinch the orange rubber seal—some clean engine oil may make this easier. Install the cable guide and verify it is aligned with the throttle cable actuator. Once alignment is satisfactory, apply Loctite® 222 to the 10-24 x 1/4″ screws and tighten to 18-22 in-lbs. 4- Install the new O-ring into the throttle body. A light film of clean engine oil can be used to help hold the O-ring in place. Align the manifold to the throttle body, use purple 222 Loctite® on the 10-24 x 1″ socket-head assembly screws (with flat washers) and tighten them to 35-40 in-lbs. 6- Using the new S&S® supplied gasket, slide the S&S supplied intake air temperature (IAT) sensor in place. Use Loctite 222 on the T10 Torx button head M3 x .5 x 10mm screws and tighten to 6-8 in-lbs. Picture 4 Picture 5 Picture 6 5 7- For the stock throttle position sensor attach the “C” shaped spacer to the end of the throttle shaft, put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, apply some Loctite® 222 and torque screws to 18-23 in-lbs. 8- Install the new O-ring on the IAC motor. Lubricate the OD of the O-ring with a light film of clean engine oil. Put a 4mm flat washer on each T20 Torx button head M4 x .7 x 12mm screw, coat the threads with Loctite 222. Install the IAC motor and tighten the screws to 18-23 in-lbs. 9- Partially install the fuel injectors in the fuel rail. Be sure to orient the black O-rings to the rail and align the clocking tabs with their holes. It may be helpful to lubricate the O-rings with clean engine oil. See Picture 9. NOTE : These are special O-rings that seal pressurized gasoline. If you see one with damage or an abrasion—replace it immediately. Picture 7 Picture 8 Picture 9 6 10- Connect the Injectors to the manifold with a light squeezing action. Lubricate the O-rings with clean engine oil. Once in place, use Loctite® 222 on the threads of two 8-32 x 5/8″ slotted panhead screws and tighten to 15-20 in-lbs. 11- Install the backing washer and O-ring on the fuel supply tube. Lubricate the O-ring with clean engine oil. When the tube is in place, position the Y-shaped clip on the fuel rail and tighten the Loctite 222 coated T20 Torx button head M4 x 7 x 12mm screw to 18-23 in-lbs – Gently push the injectors downward toward the manifold to increase clearance for connecting the wire connectors. Cut the existing injector connectors from the motorcycle harness. Slide the sleeveing onto the injector harness. Slide heat shrink tubing on to each wire of the injector harness wires. Crimp the butt splices to the motorcycle harness. Move the heat shrinks over the splices and shrink with a heat gun. Slide the sleeve into place. Picture 10 Picture 11a Picture 11b Picture 12 Picture 12a 7 13- Put the stock manifold flanges on the manifold. YOU MUST USE THE S&S® RUBBER GASKETS ON THEM. Be sure to orient the tapered end towards the manifold and the flat end to the heads. 14- Hold the manifold up in its basic mounting position and connect all of the wiring harness connectors at this time. Install the manifold using the stock mounting flange bolts (from the primary side of the motorcycle) coated with Loctite® 242 and the new S&S cam side screws (1/4″ socket head, 5/16-18 x 3/4″). If a screw longer than 3/4″ is used, damage to the heads will result. Lightly snug all four manifold mounting bolts but DO NOT TIGHTEN AT THIS TIME. Connect the throttle cables and cruise control bracket (if applicable) at this time. NOTE: The Harley-Davidson® service manual for your model motorcycle will be helpful during this step. 15- Install the breather system now. On 4.00-inch bore or smaller engines the breather uses banjo fittings with hollow bolts and connects across the heads to the intake with a T-hose. This hose will need to be trimmed and have spring clamps attached as shown in photo. Torque the hollow bolts to 10-12 ft-lbs. On 41/8-inch bore or larger engines, install the sharp bent hose on the rear head and install the check valve with the white end towards the head. Mount the other hose on the black end of the check valve and connect it to the throttle body using spring clamps to secure the connections. Picture 13 Picture 14 Picture 15 8 16- Once the breathers are secure, install the fuel line per the factory service manual you are working with. Connect the battery and verify the fuel pump turns on to pressurize the system and there are no gas leaks, but DO NOT START THE ENGINE. At this time, PC software may also be used to verify sensor readings and adjust the throttle position sensor voltage if necessary. 17- Install two 242 Loctite® coated pipe plugs (included in kit) in the air cleaner backplate as shown in Picture 16. Torque to 35-45 in-lbs. Also, two pan screws coated with Loctite® 222 must be installed in the backplate in place of the enrichment device. See Picture 16a. Torque them to 12-18 in-lbs. Failure to install these screws could allow dirt and debris into the intake system. 18- Use a new gasket on the backplate and put it in place noting the number of shims required. Once you select the appropriate shims (included) mount the backing plate to the engine but DO NOT INSTALL THE SCREWS YET
