hi Maxhdrm
where are you based? might be able to make another plan...
that said, in the next release (imminent) - expecting the 1st week of September - there will be functionality that will work great with the INNNOV, as in that the control/data wire (the 3rd wire in the connectors that is not Vbat of Ground) will simulate the Ignition switch of the bike, , i.e then you can set the timeout of the accessory output to 45seconds before the Vbat drops from the output (i.e. gives enough time after ignition trigger goes low for the camera to save all files etc before power is dropped to it too)
in your current setup, you could use a splitter on the accessory output (we intend to have some 1:2 and 1:4 splitters available soon) and just connect the whole camera to an ezCAN plug (that is with the Sept release software)
for now, to answer your question, you could very well connect the yellow trigger wire to the Vbbat output of your accessory output
best
