The two connectors in the bike's loom you need to find are:
(1) The speed sensor connector which is only accessible by removing the tank. It is white three-way connector and sits above the inlet valve inspection cover. You need to connect the inline coupler supplied in the GiPro's harness.
(2) The crank position sensor connector. This is a 2-way connector which hides under a rubber boot just behind the frame in front of the air box just above the rear brake reservoir. It is quite fiddly to get at, but can be done without removing anything. You need to tap into the grey wire at this connector.
You'll also need to connect the GiPro's red wire to a switched 12V supply. The feed to the rear brake light switch is the nearest and easiest to access. Just make sure it is the feed to the brake light switch, not the wire from the switch to the brake light or the gear indicator will only work when you apply the brake!
