I picked up a Trail Tech tachometer and hour meter for $25 on sale for Cycle Gear.
It comes with the meter and pickup wire, brief instructions, 3M double-sided mounting tape, and two hole plugs.
Here's a better view of the instructions.
The Trail Tech tach can be mounted with two bolts or screws through the mounting holes or with the double-sided tape supplied. Choose a location that will allow the signal wire to reach the spark plug wire and decide how you want to mount it.
I chose to use the mounting tape for this installation, so I applied the sticky tape to the rear of the tach. There is a little blue button on the back of the gauge which cannot be used once the tach is mounted. For that reason, it's a good idea to get the correct settings before mounting. I suggest wrapping the wire around the spark plug wire (as shown later in this article) and starting up the scooter to make sure the tach is functioning properly. Most small scooters will probably use 1 pulse per revolution. I used high sensitivity and fast repsonse as well.
It is best to apply mounting tape in temperatures above 60°F. Clean the surfrace that you will be mounting the tach on with rubbing alcohol to remove and dirt, oil, or wax residue. Remove the cover sheet, put the tach into position, and apply firm pressure. Don't push so hard that you damage the gauge. Once it's in place, you cna install the plugs that fill the bolt holes if you desire. They just press in.
Now you'll need to run the signal wire to the spark plug. Make sure it's secure and out of the way of moving parts. If passing through a hole, it needs to be protected by a grommet unless it is a very loose fit and the edges of the hole are smooth.
I zip tied my signal wire to the throttle cable since they both run to nearly the same location.
Wrap the signal wire around the spark plug wire a few times. I know with some other tachs people discuss how many wraps it takes to get a proper signal. I just wrapped it around as shown, tested, and it worked.
Now you can fire up your scooter and verify that it is working properly before reinstalling any body panels you may have removed to run the wire.
I think one of the best parts of the Trail Tech vs the Tiny Tach is that this one looks a lot more like the popular Sigma bicycle speedometers. They make a nice pair for cheap instrumentation.
