... I came back home to clean up some wiring in my bonnie that I did a couple of weeks ago. I also added a new tachometer that's been sitting on my desk for three weeks. For now, I am using the handlebar mount that came with the unit to mount the tachometer on my handlebars temporarily as shown here (eventually, I will install it to the right of the speedometer as seen
here):

I've been meaning to get a tach for some time but did not want to spend the hundreds of dollars that Triumph wants for theirs. A quick search led me to this
post in TriumphRat.net. I bought an
electronic mini-tachometer from BKRider for $43. Its usually for a Harley but it works well with my 2007 Bonnie.
The install was simple. The hardest part was finding the harness in the headlamp housing that I need to splice into. Here are the basic installation steps:
- Remove the headlamp.
- Find the speedometer harness. The trick is to trace the cable that comes out of the speedometer housing into the headlamp housing.
- Find
the following wires in the speedo wiring harness: black, green/red , red. These wires should be next to each other in the connector, numbers 7,8, and 9 respectively. The
red wire is the tachometer data line, the green/red is the ignition
power, the black is ground. Cut the wires and make sure to leave enough
room on each side for splicing.
- There are four wires in the
tachometer, blue (lamp power), red (tachometer dial power), green (tachometer data), and black (ground). Short the blue and red wires.
These two will connect to the ignition power (green/red). The green wire
will connect to the red wire, and finally the black will connect to the
black wire.
Solder the splices to ensure a solid connection. I recommend using heat shrink.
Be safe and happy riding!
