STOP RIGHT THERE!!!!
The GiPro has to be wired just like the instructions say, it does not have a memory with an internal battery backup and if disconnected from the battery it has to be reset.
It is on all the time, the display illuminates with the ignition. The battery draw is miniscule and less than the ECM.
For anyone who has one and has to unhook the battery for whatever reason, remember that the GiPro has to have the preferred setting reset. It goes back to the first setting with a power interruption. It will go back to the factory setting of power reduction in 1-3 gears.
