2 Suggested Installation Order: Install Goldwing Right Side Control (Mechanical Portion Only-Disconnect Throttle Cable at throttle drum) Optional: Install Turbo City Fuel Pressure Regulator (if you haven t already) Layout Wire Harness & Cruise Throttle Cable Fabricate Cruise Throttle Cable Bracket and Cruise Unit Mounting Bracket Prepare Extension to throttle drum Re-connect Throttle Cable at throttle drum Mount Cruise Throttle Cable Bracket Install Throttle drum extension Connect Throttle drum extension to Cruise Throttle Cable Adjust throttle operation per Service Manual with AirBox and Front PAIR Hose temporarily installed Install Cruise Unit Mounting Bracket Install Pulse Divider (Cut C8 Capacitor) Make all electrical connections required by Rostra Manual except for the control panel Route the Goldwing control cable harness and determine final length of wires to 9-Pin Connector Wire 9-Pin connector Test Continuity of wires for 9-Pin connector Connect 9-Pin connector to bike harness. Test operation of switches and buttons. Connect Rostra control wires to the 4 wires for the Goldwing control cruise operation Run diagnostics on Rostra Cruise Control Install Cruise Unit onto Mounting Bracket Synchronize starter valve per Service Manual Re-Install Airbox noting new routing of front PAIR hose to Airbox

3 Goldwing Right Side Control (Mechanical) - All plastic and the airbox should be removed. - Loosen the throttle cable at the engine side to make the cables at the right control easier to remove - Remove the right side control and reuse the throttle pipe and grip, it fits in the Goldwing control without modification - Reposition the brake master cylinder as far up the bar as possible if needed. - Test fit the Goldwing switch to determine the inclination that best suits your needs - Mark the hole location then drill the hole - Loosen the black cable ties holding the throttle cables to the bars - Install the throttle cables to the throttle pipe and install the Goldwing switch - Connector the brake switch wires to the brake switch contacts in any order. Clip the two wires with the smaller connectors, these will not be needed. Drill hole for Goldwing Switch

4 Cruise Cable & Electrical Harness Routing -Route and mount the end of cable before mounting the cruise module to the bike. Routing Overview Cruise Module Connect to output from Pulse Divider Bulkhead connectors Fig. 34 M in Rostra Manual Connect to Ignition Coil Wire Harness from Cruise Module VSS Wire (Gray) Cruise Throttle Cable Tach Wire

5 Cruise Throttle Cable Routing Cruise throttle cable through air inlet opening to reach the other side of frame. NOTE: DO NOT route wire harness here it should go under the airbox (This is an earlier photo) Securing Cruise Module Throttle Cable End - Thread the cruise throttle cable end per the Rostra Installation Manual - Fabricate a small bracket using 1/16 x ¾ x ¾ Aluminum angle stock Rostra Cruise Cable Existing Throttle Cable

- Install the cruise throttle cable to the angle bracket with the 2 lockwasher nuts provided in the kit (G18) - Re-connect Throttle Cable at throttle drum - Position the angle bracket between the

6 - Install the cruise throttle cable to the angle bracket with the 2 lockwasher nuts provided in the kit (G18) - Re-connect Throttle Cable at throttle drum - Position the angle bracket between the throttle cable bracket and locknut for the throttle cable Route wire harness here it should go under the Throttle Cables Pair hose under throttle cable Secure cruise throttle cable with cable tie through existing hole - Remove the PAIR valve hose from the left valve cover. Place the airbox end under the throttle cable. - Temporarily install the airbox to verify proper throttle operation (no binding) at full left and right steering lock. Adjust as needed.

Cruise Cable/Throttle Drum Interface According to the Rostra manual the throttle must have at least 41mm of travel from closed to fully open throttle{pg 10}.

To minimize the fabrication I used a machined servo horn designed R/C models: -Futaba Single Aluminum Horn Silver 1.5" (http://www2.towerhobbies.com/cgi-bin/wti0001p?

7 Cruise Cable/Throttle Drum Interface According to the Rostra manual the throttle must have at least 41mm of travel from closed to fully open throttle{pg 10}. The ST1300 has less than 30mm of travel so you must mount an extension to the throttle drum to get the required travel. The extension should not interfere with the airbox when re-installed. To minimize the fabrication I used a machined servo horn designed R/C models: -Futaba Single Aluminum Horn Silver 1.5" ( Drill out to match the throttle drum shaft diameter File down boss to ½ height Drill out to match shoulder screw Rubber washer to take up slack Shoulder Screw Do not reinstall split washer Boss toward rear of bike. File down to ½ height Add Internal tooth washer this side

Clocking the extension 90 45 The throttle drum will rotate through 90 degrees from fully closed to fully open so clock the extension according to the diagram on the left.

8 Clocking the extension The throttle drum will rotate through 90 degrees from fully closed to fully open so clock the extension according to the diagram on the left. Connect Throttle drum extension to Cruise Throttle Cable - Install the Eyelet connector (G8) with the shoulder screw to the throttle drum extension - Install one bead chain connector to the cruise throttle cable. Preposition the bead chain connector cover (G5) - Measure the length of bead chain (G3) that will be required (I used 3 beads) - Preposition a bead chain connector cover on the bead chain and install through both bead chain connectors. Move the bead chain connector covers into position.

Pulse Divider Installation This circuit is designed to both amplify and reduce the frequency of the signal from the VSS. The output signal from VSS is approximately 80,000 pulses per mile.

Additionally, one capacitor (C8) needs to be clipped off the circuit board to disable the low-pass filter.

9 Pulse Divider Installation This circuit is designed to both amplify and reduce the frequency of the signal from the VSS. The output signal from VSS is approximately 80,000 pulses per mile. To modify the signal to a range acceptable for the Rostra Cruise module move the jumper to the divide by 2 position. Additionally, one capacitor (C8) needs to be clipped off the circuit board to disable the low-pass filter. Clip both leads of the C8 capacitor and remove Move the jumper to the divide by 2 position Connections: 12V Fused 12V. The Quartet harness is acceptable. Ground Vehicle Ground Output from Pulse Divider Connect to Gray Wire of the Rostra Cruise Bundle {Page 19 F. } From VSS Connect to Pink wire with Green strip. (24-Pin connector. Bike side of the connector) From VSS: Connect to Pink wire with Green strip

10 The pulse divider should fit between the cruise module and metal frame

12 Cruise Module Mounting Please note that the Rostra manual specifically states to never mount the unit with the cable pointed down which is precisely how this is being mounted. I am assuming they state this so condensation and water do not infiltrate the connector and throttle cable housing interfaces. I removed the connector and added dielectric grease in the contact area. I m making the assumption that the throttle cable interface will never see the harsh underhood environment of an automobile. This mounting orientation doesn t effect operation. Fabricate a flat mounting bracket using 1/8 x 1½ Aluminum Flat Stock. Use the diagram and photos below to determine the hole locations and final installed orientation. Note the fasterners that were removed to gain access to this area. The bracket will be mounted with one fastener to the pentagon-shaped fairing support. Use a fastener with a low profile head. Use a fastener with a low profile head Insert the selfthreading bolts provided with kit Mounting Bracket Orientation (Looking from left side toward tank)

13 Mounting Bracket Installed (Looking from tank toward left side) Note: Do not install the Cruise unit onto the mounting bracket unit all switch settings have been made and diagnostics have been performed to verify operation per Page 20 & 21 in the Rostra Manual. Insert the self-threading bolts into the unit once before final installation so that the threads can be formed. You will need to use force to separate the two fairing components when you do the final install of the Cruise unit.

14 Final Installed Location & Position Note: The throttle cable and wire harness must hang below the top of the radiator to avoid the space occupied by the left storage compartment.
