2003 Extend-cab TRD edition dashboard wiring harnesses

Hello

Main dashboard wiring harness that contains 3 sub-harnesses.

I have identified 6 out of eight colors (speaker pairs) covering RF, RR, and LR in one sub-harness.
However, there are only six from that sub-harness- no LF pink/violet.

The second sub-harness contains a black-striped white, a red striped black, a blue-striped pink, and a brown.

Third is shielded grey-striped violet with violet and green wires within the metal shielding.

Testing the black-striped white, a red striped black, a blue-striped pink, and a brown in every configuration does not detect power. Key is on + tested with engine running.

Also what is the function of the grey-striped violet wires?

Any help appreciated!
