its really not that hard to add a relay, in laymans terms heres what u need to do to wire it up properly
prong #86 goes to any wire that has constant power when u turn on ur motorcycle, easiest wire to "tap" into is the key cylinder. look for the wire that gets a constant 12V when u turn the key to the "on" position and not a constant 12V when the key is OUT becuase that would be a 12V constant wire, or a wire where u see 12V when the engine cranks and 0V when the engine stops cranking as that would be the ignition wire or a wire that is just 0V no matter which position the key is in as that would be the ground wire
prong #85 gets grounded
prong #87 goes to the + terminal of the battery, dont forget to add a fuse in between
prong #30 goes to the positive + cable to ur camera
the - cable from ur camera u can ground it anywhere
so now when ever u turn the key to the on position, the relay will switch and power on ur camera where it is drawing power directly from the battery, not from things like headlights or horn... or in some cases in cars, ppl wire the camera into the airbag fuse...........................................
