2006 mustang head unit

I am replacing my stock head unit in my 2006 mustang with the shaker 500 system and need a litle help on wireing.

I am a little confused on the remote turn on wires from the Metra large plug that came in the 70-5521 kit. I have the voltage regulator to stop the turn on pop and read all the stereo threads I could find. I see the remote wire from the head unit goes to the voltage regulator, but does the blue remote wires from the large Metra plug get connected or used ?

Is there a white stripe on the blue wire of the large plug?

The blue wire on the 24 pin connector is not used. The 8 pin connector is not used at all.

If you using the two little shaker 500 amps in the drivers foot area that power the subs in the doors and the aftermarket amp is used else ware?

The blue wire on the 24 pin connector is not used. The blue/white wire on pin 4 of the 8 pin connector needs the remote power from your aftermarket HU with the voltage reducing regulator. The aftermarket amp will need the same remote power from the head unit. Just be sure that the remote power for aftermarket amp is taken between the HU and the voltage regulator and not after the regulator.

On a side note if you have and want to continue to use the 3.5 jack in the console and your aftermarket HU has Aux audio RCA inputs you will need 70-5520AUX.

Also an antenna adaptor will most likely be needed.
