Need help with installing battery cables

[Tpilover]

I just finished putting in a motor due to buying a supra with a siezed motor.
After swapping the motor out I realized it's missing a positive cable. I'm needing help with the wires below and if they both attach to the positive size or one to positive and the other negative.

This one is coming from below the fuse box. I'm pretty sure it's positive.

This one is coming from the grounds on block and starter.

Any help would be greatly appreciated.

that blue wire is the charging wire just splice it with the rest of the positive wires

the ground comes from the back of the intake manifold the the one from the starter go's to the Positive you will also have a black wire from the body that will go to the positive on the battery and a large black wire from the junction box to the alternator output bolt
