I completed my K2 installation a few days ago, so wanted to share my pics and experience in case it can help anyone else contemplating a K2 install on a Harley Street Glide or similar bike. My goal was a neat, clean install with the wiring and cameras out of sight to the greatest extent possible.
From the front view, the forward-facing camera is not readily visible. The camera is located between the headlight and the right turn signal and is mounted to the Kuryakyn driving lights.
The rear camera is mounted to the upper left license plate using the existing fastener.
The camera cable then runs down under the license plate bracket and through the fender. I notched a small hole in the hard rubber license plate bracket so the camera cable would fit between the bracket and the gasket.
This shot shows the underside of the rear fender where I drilled a hole to accommodate the rear camera cable. I actually had to drill two side-by-side holes and then file them into one oblong hole to accommodate the rectangular plug on the DVR end of the cable. WARNING: Drilling into the fender on a relatively new bike is not for the faint of heart!
Once I ran the cable through the hole, I used some leftover white Sugru (moldable rubber) to fill the hole and to protect against any chafing since a typical rubber grommet wouldn't fit the irregular hole. The cable then runs up the right side of the rear fender where it’s tiewrapped to an existing cable harness, then under the seat, along the left side of the battery, and then into the wiring harness under the fuel tank.
A previous forum poster recommended protecting the front camera from flying debris. Since the K2 replaced a BikerCam I had previously installed, I cut off the front protective cover and lens from from the BikerCam, and slid it over the front K2 camera. There is no degradation in video quality other than some very slight darkening of the image at the four corners. I can live with that for the piece of mind this protective shield provides.
The Kuryakyn driving lights also include a wiring channel where I could hide the front camera wire until it was inside of the outer fairing. Nice and clean.
I wanted to mount the DVR someplace that was easily accessible since I figured I’d be removing the SD card on a regular basis to download videos. I looked at mounting the DVR under one of the side covers, but there’s not much room, and I have to remove the saddlebags to remove the side covers, so not very convenient place for DVR. So I decided to use the Kuryakyn left lower fairing door pocket I recently installed.
The K2 DVR fits nicely within the pocket, even with all the cables plugged in. As shown above, the Kuryakyn bag also includes an elastic inner pocket which minimizes movement of the DVR during acceleration/deceleration.
This next photo shows the DVR wiring, which is neatly tiewrapped to the left front engine guard. I installed the GPS at the top left inside the outer fairing where it could sit horizontally. I have no problem acquiring a GPS signal while bike is in garage, which is more than I can say for my Sirius signal where the bike has to be outside with minimal overhead obstructions to get a decent signal.
The front camera wire also runs behind the outer fairing. The two wires running to the rear of the bike behind the gas tank are the rear camera wire and the DVR power wire, which runs to the K2 DC-DC converter.
The converter is located at the front of the main harness wire trough tray located under the fuel tank. There was enough room in the tray for the converter under the tray cover and that spot seems to be a good centralized location as the wiring to the battery and the trigger cleanly run down the tray.
I originally installed the K2 with the Power Hub 2 (installed under the seat as shown below). I experienced some anomalies with my rear speakers cutting out after that, which may be related to the Power Hub, may be due to the local heat, or may just be coincidence, but the issue with the speakers started immediately after the K2 install.
Since I was only using two of the five output wires from the Power Hub (one for the K2 DC-DC converter power and one for a cooling fan), I decided to remove the power hub.
Instead of connecting the K2 converter directly to the battery, I purchased and installed a delay off relay/timer between the converter and battery as discussed in the K2 forum thread on battery drain. I installed the timer behind the right side cover where it could easily be wired to the battery, trigger (switched power), K2 wiring, and ground. That seems to be working well. The timer allows the DVR to shutdown gracefully so all files are saved when shutting the bike off at the end of a ride, while preventing any parasitic draw from the battery when the relay is off. I used the ground post behind the right side cover for the relay and K2 converter common ground.
If you’re doing a similar installation and have any questions or recommendations for improvement, feel free to drop me a note.
