I haven't finished my motorcycle conversion yet but I am close so I figure I'll ask ahead of time. How do you wire an amp meter? I will have a 48 volt system with a 200 amp fuse 300 amp controller, 300 amp motor (peak). I know I need a shunt, I plan on getting a 200 amp one, but how do you wire it up.

I am guessing the shunt splits the positive wire coming from the battery probably after the fuse using the two bigger bolts on the shunt. Then do I just connect the amp meter to the two small bolts and Bob's your uncle? Or do I have to wire it to something for power. The meter I am looking at has four wires, Blue, Green, Black, Red.

The Blue and Green say input, I assume those go to the shunt's small bolts. The Black and Red are positive and negative for 5 volts of power, where do I get the power from, I will have the stock 12 volt battery in the vehicle as well, do I wire it up to that?

Please be gentle, I am learning.
