Which wire goes to the starter solenoid?

[Winglessflight]

I need to run a starter jumper wire from the fuse box to the starter solenoid (Automatic car). Do i use the thick white wire coming out of the 30A fuse in the fusebox? If not, which one?

scratch it, i'll just run a jumper from the starter solenoid with a 30A fuse on it's own line. Close thread.
