Here is my installation of Innovv K2 for a small displacement scooter (Suzuki Address 115)
DVR under the seat (Still have no idea how to sort out the wires properly but since it is a small scooter, I do not have much space).

FRONT CAMERA UNDER THE RIGHT BRAKE LEVER:

REAR CAMERA ON THE PLATE NUMBER LIGHT:

GPS ABOVE THE TAIL LIGHT:

Actually I felt that the 1.5m is short infront, had to be good in wire length management so I ended up installing it under the brake lever. For the back it has much allowance.
I let the cables pass under the floorboard then at the compartments.
Looks cool, both cameras with 2.5 meter and 1.5 meter video cables are too long for the scooter.
You may can tie up the excess wires and attached on the wall beside of DVR.
