Was it plug and play or do you have to splice into a power wire?
For the HealTech unit, you have to splice into two different wires. The kit comes with two IDC connectors, so they make it easy to tap into the wires.
You tap a crankshaft position-sensor wire, and a switched +12V wire. Then you just find the right connector under the tank (triangular cross-section shape), and plug the Healtech connectors in.
First thing after install is to teach the unit, which is just going through all the gears (slowly) 1 to 6.
The unit shows a "-" when the clutch is in, or the transmission is in neutral. If you hold the clutch in and downshift approaching a stop, from say 3 to 1, you will only see the "-" until you let the clutch out again. A trick is to barely engage the clutch for just an instant after stopped, and the unit will briefly show what gear you're in. (To make sure you're all the way in 1st without having to bang the tranny. And that's another trick, these trannies can be hard to get into 1st if you're already stopped, so let the clutch in/out just a bit, and you can find 1st.)
You can fine-tune the rate at which the unit updates the next gear, which is pretty cool. From the factory it may be a split-second slow to update the gear. But as said, you're not watching it change anyway, you're watching the road. You will just glance down occasionally to verify the gear.
The unit works great, it never loses track of a gear! It's really nice having confidence of what gear you're in...especially 5 and 6. And, it frees-up a bit of brainpower, not having to keep mental track of the gear.
I mounted mine in the same place as steelrider.
