Installing a Kennedy Cellset MC/SP4

I decided I wanted to be able to use my cell phone while riding. Mainly to recieve calls since I often have young kids with sitters. I wanted something that would be as hands free as possible. After looking around, I decided that the Kennedy Technology Groups, Cellset MC/SP4 would do what I needed. When you order, you will want to get the Universal 5 pin model. Some are specific to the GL1800 and GL1500 Goldwings. They will ship in separate packages depending on what you order.

In order to use this, you must have a cell phone that is compatible. Most of the newer phones are. Visit to read more about which phones will work. Since my phone had the correct size jack and could be set to auto-answer, it would work perfectly and would be completely hands free to receive a call. When a call comes in, I get a short ring tone in my helmet speakers, then the phone auto-answers. At this time, myself and my passenger can talk to the caller. For calling out, I use the phones speed dail so I simply have to press 1 to call home. The rest is the same as recieving a call. Seems to work very well.

Below is how I installed mine. Keep in mind that due to different phones and locations riders may wish to place the phone, your installation could be entirely different. Use this as an example of how this can be installed.

The first step is to determine where on your bike you wish to keep the phone. Some may wish to get a handlebar mount. Or maybe put it in a tank bag, or maybe leave it clipped to their belt. I decided for my installation I would use the left side pouch of my windshield bag. This keeps it high enough to best get a signal, allows me to extend the antenna, and if I wish to speed dial, I can use my left hand to do so.

For the most part, the instructions are fairly easy to follow. I deviated slightly from them which I will cover as I go.

First, inside the MC/SP4 unit is a switch that must be set to match the Intercom Harness you are using. A tag on the harness will read either SW IN or SW OUT. Remove the four screws on the MC/SP4 to access the switch and set it to either IN or OUT depending on how your Intercom Harness is labeled. Although not instructed to do so, I put a bead of silicone sealant around the edge of the case before replacing the lid. I did this just in case water found it's way into my fairing.

Next, the instructions say to plug the Intercom Harness into where you now plug your helmet, and then plug your helmet into the other end of the Intercom Harness. The problem I had with this is that the stock Yamaha plug has a nice weather boot with a cap on it. The Kennedy Intercom Harness has no weather boot or end cap which bothered me. Allowing rain to get to that when not plugged in was asking for trouble in my opinion. For what this thing costs (about $210), you think they would have a weather boot on the plug.

So, I decided instead to mount the unit inside my fairing and place the Kennedy Intercom harness inline coming from the Yamaha audio components and keep my Yamaha intercom plug in place.

First, remove the fairing as shown here:

Locate the plugs marked with red tape coming from the audio unit. Unplug these and plug the Kennedy Intercom Harness in here. I used electrical tape around each plug to help weatherproof them as well as prevent them from coming unplugged.

Next, I placed double sided tape on the back of the MC/SP4 and mounted it near the center of the fairing under the audio unit as shown in the photos below.

Next plug in the Intercom Harness, Power Harness, and Cell Phone Harness as shown below. Place some double sided tape to the Intercom Harness box and mount as shown.

Next, route the Cell Phone Harness to the location you plan to mount your cellphone. This could involve other work like removing the gas tank or seats depending on how you need to route the wire. In my example, I am placing the phone in a windshield bag so I routed the wire between the dash and fairing/windshield.

Next, you need to wire the Power Harness into a power source. I spliced into the hot wire going to the fairing Aux Power outlet. There are no fuses needed. The Cellset uses a solid state, auto-resetting, 1/4 amp fuse.

Now neatly tie back all wiring and place them as close to the center of the fairing as possible to avoid trouble getting the fairing shell back on.

It would be wise to test the unit now before re-installing the fairing. If you can recieve a call into your helmet and both parties can hear clearly, now re-install the fairing cover.
