You have 1 main (large) wire from battery (+) to large connector on starter (+) and 2 smaller ones (maybe) with a black round thing on it (fuseiblelink) those 2 wires goes to the large connector at the starter (same as the large from battery) cause those 2 are main power supply to the fuseterminal inside the car (and also power to the purple turn/on ignition)
I made a diagram below here, what I wrote above is from an 1989 Camaro but it
should be similar and/or the same on your car.
There should be 2 black/red ones and 1 purple (small wires) is that correct ?
Correct me if im flying way off someone :-)
