Quick reminder. I am a newbie and this is my first bike. That out of the way.. Woke up this morning and decided to take out my battery box. I had an electronics box made so I had to take it out at some point. The box came out relatively easy but I had to unplug a bunch of things I have no idea what they are for which raises some questions. I should mention that I will also be installing a Motogadget M-unit (and rewiring) to simplify the wiring although at this point I am not sure which wires from the old harness should go in the bin and which ones can stay. Here are some questions off the bat 1)what are those 2 things circled? They came off with battery box. Do I need them? 2) does that tube connected to that filter REALLY have to be that long? Can I cut it short so that it tucks in neatly 3) bolted to the underside of the battery box was another box that just said IGNITION on it. What exactly is it and do I need it with motogadget? 4) since I will be rewiring, what type or gauge of wiring should I be looking for. Motogadget sells their own cable kit but it's over $100. I want to see if I can get cheaper type at my local auto stores.
