We do not recommend using any Rostra cruise control systems on motorcycle, ATV, or other non-automotive applications as we do not validate the operation of these units on these vehicles. Due to safety concerns surrounding these installations, Rostra representatives are unable to provide technical support on these applications.
Located below this FAQ section, you will find installation manuals for each product Rostra Precision Controls, Inc. manufacturers including aftermarket cruise controls, Magna/RearSight® backup camera systems, BackZone Plus ultrasonic parking assist systems, ComfortHeat seat heaters, ComfortSeat automotive lumbar support, and ComfortSeat vehicle seat massagers.
To acquire both vehicle speed signal (VSS), brake wire, and tachometer wiring colors and locations, please use our VSS Search to the right. If you do not see your vehicle listed, please download Rostra forms Form #4428 (for vehicles built between 1996 and 2009) or Form #4429 (for vehicles built between 1986 and 1995).
The majority of Rostra-manufactured cruise controls systems are sold as complete kits. As well, Rostra manufactures universal cruise control units that often require the purchase of additional items to function with certain vehicles including vehicle speed signal (VSS) generators and control switches. To get a listing of exactly what parts will be necessary for your vehicle, please use the Vehicle Search menu at the top of the page or download our yearly catalog. If you have questions about a customized cruise kit or other vehicle applications, feel free to call our Customer Service department at (800) 782-3379.
The LED is a surface-mount light on the circuit board to the left of switch number ONE of the programming switches.
The programming switches are located under the black rubber grommet on top of the cruise module. (See images below)
Gain is how the cruise control reacts to both road conditions and engine size. Always start at the factory setting which is Mid-Gain. If the vehicle surges while the cruise is engaged, you will need to adjust the gain setting. A fast surge, when the vehicle speeds up rapdily above the cruising speed, requires the gain to be lowered. Set the gain to Low or Extra-Low if needed. A slow surge, where the vehicle slows well below the cruising speed, requires the gain to be raised to High.
Engine/Setup Timer is how fast the cruise control retracts the cable once the cruise is set. Always start at Low. If the vehicle drops below the set cruising speed but then recovers, set to Medium. Set to High or Extra-High if still not acceptable.
RF steering wheel-mounted switches can be installed on several vehicles, but are not recommended for every vehicle. To find out if your vehicle has an RF switch available, check out our application guide.
Have no fear! Just because your vehicle is not listed in our application guide doesn't necessarily mean we don't offer a cruise control kit for it. Call our customer service department at (800) 782-3379 for specific application questions.
The use of LED tail lights requires a five-function automotive relay to bypass the brake system. LED tail lights do not let the violet wire (cold side of the brake switch) see ground through the brake lights, themselves. Wiring in a relay is as follows:

All settings are based on 1/8-inch slack in cruise control cable. More slack will cause the cruise control to surge or lose speed once set.
