According to the above diagram, the pink wire in the factory harness to the "amplifier" provides the power. I am unsure which year service manual the diagram is from, however. (Your vehicle may not have the "amplifier switch" pictured in the diagram with the white wire in the harness.) The factory pink wire is the "remote turn on" wire (or commonly referred to as the "power antenna" wire), so the corresponding wire in the aftermarket harness should be the blue wire (or perhaps a blue wire with white tracer). Just out of curiosity, are you using the stock speakers, or do you have aftermarket replacements?
