I m not an electrician, but i have hooked up accessories without blowing up my bike.

Based on the pictures, this is not hooked to the flasher relay. Leave that one alone. It only controls the turn signals.

You buy a new automotive relay at any electronic store. What it does is has four or five terminals you attached wires to. One wire comes from the battery straight to the relay. One goes from the relay to a grounding point. One is a switched wire that has been tapped into another wire only powered on when the key is turned (ie the tail light wire). The final one or two terminals provide power to what accessor(ies) you are hooking up.

This allows you to leave the accessory plugged in and power will only be supplied when the switched wire has power to it. That flips the relay to connect the power from the battery to the wire going to the accessory.
