Why use Murphs CCS-100 Cruise instead of the Rostra Electronic Cruise ?

Murphs CCS-100 controls engine speeds using a tachometer signal and

engine vacuum to control vehicle speed.

The Rostra Electronic Cruise uses a VSS (Vechicle Speed Sensor) signal,

and a tachometer signal to control vehicle speed. The Rostra needs both

signals to operate.

Older vehicles and many motorcycles don’t have a VSS (Vehicle Speed

Sensor. If you want cruise on any manual transmission vehicle without a

VSS (Vehicle Speed Sensor Murphs CCS-100 Cruise Control is the simplest

solution.

On vehicles with a VSS (Vehicle Speed Sensor) you can use either Murphs

CCS-100 Cruise or the Rostra Electronic Cruise.

Use the Rostra Electronic Cruise if you live at high altitudes. Some have

reported problems holding speed at high altitudes with the original

CCS-100 due to lower vacuum at high altitudes. Then again, others have

reported no altitude problems at all.

How the Murphs CCS-100 Cruise Works

The cruise monitors engine RPM through the blue wire connected to your

tachometer or coil wire. Without a tachometer signal the cruise won’t work.

The Cruise servo cable uses engine vacuum to move your throttle. Without

engine vacuum the cruise won’t work.

The purple or brake light wire allows the cruise to turn on and shuts the

cruise off when you apply the brakes. If the purple brake wire is not

connected correctly the cruise either won’t turn on or won’t shut off. You

can always shut the cruise off by turning the cruise off at the control

keypad.

To summarize, you need a tachometer signal to the blue wire, engine

vacuum connected to the servo, and the purple brake wire connected

correctly for the cruise to work. If you don’t have all three, the cruise won’t

work.

Before you start your Installation Do some online research. The Murphs CCS-100 and the original Audiovox CCS-100 have been successfully installed on thousands of vehicles. A simple Google search might find online instructions already posted on your vehicle. Just search for your vehicle ccs-100 cruise control installation or your vehicle cruise control. Another good source for information on cruise control installation is the numerous online vehicle specific forums. See if your vehicle has an online forum.

If you are doing a cruise installation without following someone’s instructions you might need a copy of the wiring diagram for your vehicle. Do a Google search, it might be online. You need to know the wire colors of the following: The negative terminal of the coil wire color or the vehicle tachometer wire color. (The blue tachometer wire from the Cruise Control is connected here) A switched power source, a circuit that turns on with the key.

Servo Dip Switch Settings: You need to set the servo DIP switches inside the servo housing for the cruise to work. You can’t just pull the servo out of the box and install it….the cruise won’t work. If you are following written instructions for your vehicle, set the dip switches as in the instructions. If you are using Tach only for your signal source, remember to pull the Black jumper to the left of the Dip switches inside the servo.

Throttle connection: For automobiles, use the connection methods as described in the original CCS-100 manual at http://www.murphskits.com/catalog/docs/cc100_ins.pdf Motorcycles normally use either Throttle Wire Loop (Part # 29 in the original CCS-100 instruction manual) or the bead chain eyelet (Part #25 in the original CCS-100 instruction manual). Throttle Wire Loop example: http://www.murphskits.com/catalog/docs/audiovox/index.htm Bead chain eyelet example: http://www.murphskits.

it sticks, fix it before you ride. The cruise does not have to be on for the throttle to stick. Should the throttle ever stick, pull in the clutch first then hit the kill switch. Don’t expect the brakes to stop the motorcycle with a stuck throttle; most motorcycles are just too powerful. Vacuum Canister: You’ll need a vacuum canister. You can make one but if it leaks, the cruise won’t work. We suggest you buy one when you get your cruise control to use at least temporally for initial testing.

How to hook up the brake SPDT relay is here: http://www.murphskits.com/catalog/docs/tail_light_relay.doc Note: The motorcycle taillight brake wire color of Blue with a Red Stripe before the connector and solid Blue after the connector is for a Kawasaki C14 only. Your taillight brake wire color will be different. It is CRITICAL that you verify that you have a good connection between the SPDT relay and the motorcycle brake light wire.

Note: You can’t road test the cruise control with the bike running on your centerstand. The cruise control has a built–in over-rev feature, it will shut its self off before you know it’s actually working. The Test Ride: Wear all your gear just in case. Should the throttle stick, pull in the clutch first then hit the kill switch. Don’t expect the brakes to stop the bike with a stuck throttle; your bike is just too powerful. The cruise will operate in any gear above about 30 MPH.

If you don’t have a faster flashing LED, then you don’t have a good tach signal or the DIP switches in the Servo are set wrong. Check for a good connection at your Tachometer source. It’s fairly easy to not have a good connection when using the Scotch lock connectors. The Scotch lock connector needs to fit all the way over the wire you are connecting to and the other wire needs to be fully in the top side of the Scotch lock connector. Pull on the wires…If they come loose you found your problem.

If the Red LED inside the servo is continuously lit when you to turn the vehicle key on, try removing the purple wire from the circuit. If the Red LED inside the servo shuts off, either the brake lights are stuck on and you need to readjust the brake switch or you need to use a SPDT relay in the brake circuit. If you already have a SPDT relay in the brake circuit, either you have the wrong relay or you have it connected wrong.

You need to increase Sensitivity Settings on the DIP switches. The original CCS-100 instructions call the Sensitivity Settings Low, Medium and High. They really should be called Slow (Low), Normal (Medium) and Fast (High). The faster the sensitivity, the less the speed drops. Cruise works but is too jerky at low speeds When using just the tachometer signal, you have to make a trade off in the Sensitivity Settings. The cruise can be somewhat jerky at low speeds (30 MPH or so).
