Power supply circuit The power supply circuit obtains power from the battery (12 V) to supply the power (5 V) that is required for operating the ECU. B. Input interface circuits The input interface circuits convert the signals output by all the sensors into digital signals, which can be processed by the CPU, and input them into the CPU. C. CPU (Central Processing Unit) The CPU determines the condition of the sensors in accordance with the level of the signal that is output by the respective sensor. Then, the signals are temporarily stored on the RAM in the CPU. Based on those stored signals and the basic processing program on the ROM, the CPU calculates the fuel injection duration, injection timing, and ignition timing, and then sends control commands to the respective output interface circuits. D. Output interface circuits The output interface circuits convert the control signals output by the CPU into actuating signals for the respective actuators in order to actuate them. They also output commands to the indicator and relay output circuits as needed.

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.

throttle linkage with no cable modification. S&S Super E and G carb kits for 1936 to 1989 Big Twins contain a throttle cable guide (11-2339) designed for butterfly type throttle cables, and kits for 1990 and later Big Twins contain a taller throttle cable guide (11-2338) designed for CV type throttle cables. See Picture 2. The two throttle cable guides are interchangeable on the carburetor body, and can be changed very easily to update older carburetors or to accommodate custom throttle cables which are not stock for a particular year chassis. 1981 to Present Sportster Models Stock Sportster models from 1981 to 1987 have two cable throttle system designed for butterfly type carburetors. Sportsters from 1988 to present have a two cable throttle system designed for use with the stock constant velocity (CV) type carburetor. Since the taller #11-2338 cable guide bracket can not be used on a Sportster chassis due to insufficient frame clearance, throttle cables on Sportsters originally equipped with a CV type carburetor must be changed to butterfly style cables. S&S can supply the correct style throttle cables. See S&S Throttle Cable Application Chart.

S&S Throttle Kits S&S throttle kits fit 1″ handlebars and can be used on most chassis. (An adapter sleeve is available for use with earlier, 7 ⁄ 8 ” OEM handlebars originally equipped with internal throttle cable.) Barrel fittings on S&S cables readily “plug in” to S&S Super E, G, and stock H-D 1981-’90 butterfly type carb throttle linkage. Kits include one opening and one closing side cable, left and right grips, and handlebar clamps. Kits with 36″, 39″, 42″, or 48″ length cables are available. Length specified refers to overall cable length. Vinyl covered outer housing is 4″ shorter than overall length

REMOVAL To prevent accidental vehicle start-up, which could cause death or serious injury, disconnect negative (-) battery cable before proceeding. (00048a) 1. Disconnect battery cables, negative (-) cable first or remove the main fuse following the instructions in the service manual. NOTE When performing cable disassembly procedures, make careful notes as to the existing cable routing. Pay special attention to existing cable strap locations before removing so new straps can be placed into the same locations. Do not remove or install the master cylinder assembly without first positioning a 5/32-inch (4 mm) thick insert between the brake lever and lever bracket. Removing or installing the master cylinder assembly without the insert in place may result in damage to the rubber boot and plunger on the front stoplight switch. (00324a) 2. See Figure 1. Place the cardboard insert between the brake lever and lever bracket. 3. See Figure 2. Loosen cable adjuster jam nuts. Turn cable adjusters in until they are as short as possible. This will provide enough slack for easy removal. 4. Remove the right upper and lower switch housing screws INSTALLATION Throttle and Idle Cable Installation 1. See Figure 3. Apply graphite lightly to the throttle grip inside the switch housing and on the throttle end of the handlebar. NOTE The throttle control cable has a larger diameter retaining ring crimped to the cable end than does the idle control cable. For assembly, apply a drop of light oil on the retaining rings of the crimped inserts. 2. See Figure 7. Push the throttle cable housing and retaining ring into the larger hole of the switch housing, located in front of the tension adjuster screw. 3. Push the idle cable housing and retaining ring into the smaller hole of the switch housing, located behind the tension adjuster screw. 4. Push the throttle and idle control cable housings into the lower switch housing until each snaps into place. NOTE For models not equipped with factory-installed cruise control, if the friction shoe has fallen out or become dislodged, install the shoe with the concave side facing up and position it so the pin hole is over the point of the adjuster screw. 5. Push the throttle control grip over the end of the right handlebar until it bottoms against the closed end. Rotate the grip until the ferrule notches are at the top. To prevent binding, pull the grip back about 0.12 inch (3.2 mm). 6. See Figure 3. Position the lower switch housing beneath the throttle control grip. Install two brass ferrules (Item 3, Figure 11) from this kit onto cables, seating the ferrules in their respective notches on the throttle control grip. The cables must be captured in the grooves molded into the grip. 7. Position the upper switch housing over the handlebar and lower switch housing. Route the wire harness conduit through the depression at the bottom of the handlebar. 8. Tighten the upper and lower switch housing screws finger- tight. 9. Position the brake lever/master cylinder assembly inboard of the switch housing assembly, engaging the tab on the lower switch housing in the groove at the top of the brake lever bracket. 10. Align the holes in the handlebar clamp with those in the master cylinder housing and tighten the lower screw and flat washer finger-tight. Position for rider comfort. Beginning with the top screw, tighten the screws to 60-80 in-lbs (6.8-9.0 Nm)
