PAC RP-CH11-A to a Pioneer MVH-S622SB

[Chessiesarebest]

I am installing a Pioneer MVH-S622BS stereo in my 2005 Chrysler 300C. I am using the PAC RP4-CH11-A wiring harness. The wiring harness has an extra yellow (battery+12v) wire and an extra black (ground) wire that are not on the Pioneer wiring harness. Should I cap the extra wires or wire all the yellow together and wire all the black together? Please advise...

Run a wire from the battery or use an empty slot in the fuse box to that yellow wire with a 3a fuse.

For the black wire; crimp it in a round terminal and bolt it on bare metal.
