moin, I’m currently driving a Honda Rebel 125. It has an 11 hp 4 clock motor as 2 cylinders. Since the factory only has a speedometer installed for the speed indicator I wanted to retrofit a rev indicator. I ordered one from Amazon, but there was no description of how to connect it correctly. It has 5 ports, 2 are more understandable way for the battery. But for the other 3 I can’t find a solution.
