Installation onto your motorcycle's tail section
Included universal mounting plate is compatible with all flat, tubular steel rear luggage racks, including all rear racks from SW-MOTECH, Five-Stars, and Fehling. Adapter kits (sold separately) are available to fit the Coocase onto many other aftermarket and original rear racks.
If your bike is equipped with a "sissybar" or passenger backrest, you may need to remove it in order to provide clearance for the Coocase to open when installed. Contact Us to confirm fit on your bike prior to purchase if you have a sissybar.

Electrical Wiring Installation
Coocase is 100% compatible with CANBUS equipped motorcycles!
Every topcase includes our standard wiring kit. The standard wiring kit includes all connectors, fuseholders, and wire required for easy hookup without tools - no wire cutting, stripping, or crimping needed! Just connect 2 wires to your battery terminals and 2 more to your tail light and brake light, and you'll ready to ride.
Use of alarm and keyless entry requires that the case's wire harness be connected to your motorcycle battery. Installing Coocase's tail lights and brake lights is not required for use of the alarm and keyless entry features.
Electrical Power Draw
Because the lights in the topcase are LEDs, they draw very little power (less than 1 amp). The topcase draws 110mA when the alarm is sounding, and 16mA when the case is charging. The alarm sounds for 1 hour before it silences itself.
Most motorcycles and scooters have batteries with a capacity between 7 and 20 amp/hours. Suppose you have a small, undercharged battery with a 7 amp/hour capacity. If the alarm goes off for 1 hour (110mA) and then turns off and charges the topcase (16mA), the battery will last approximately 430 hours (18 days) before completely discharging. As long as you're riding your bike a couple hours of week, you will have no issues with the Coocase draining the battery. If your battery is larger, you'll be able to go longer without riding it (but who would want to do that?). Removing the topcase prevents battery discharge if you park the bike for many weeks. However, you should probably put the bike on a charger if you tend to do this, regardless of whether you've installed a Coocase.

Probably the biggest thing I want to say is; aside from the quality of this unit (which in my book is 5/5, I will tell the readers that Twisted Throttle's Customer Service team is EXCELLENT and assisted me with several problems I encountered. My case is a heavy use so there was a lot of wear and tear on it that required some service calls but ALL of them were addressed in the best manner by TT staff. I highly recommend this case and purchasing it from Twisted throttle. (Posted on 13-02-03)
