I'm building my Vitesse up basically from a box of bits mechanically. I've fitted a new wiring loom and upgraded to a Powerlite pre engaged starter motor. So, I am thinking the brown wire on the loom needs the terminal changing from a spade fitment to a ring terminal so that it can join the battery fed cable on the stud. Then the small white/red cable connects to the small terminal . But, I also have a black earth cable with a ring terminal on it. There is no obvious place on the starter motor to put this., Do I just earth it some where that is convenient, Any ideas?
