Thanks for sharing this. I was looking for this information a few days ago. The salesman at the dealership did not know the answer to the location of the aux wiring.
Placed my deposit today. I added it to the tracking sheet.
$1000 Deposit. Reliable Toyota in Springfield MO. Paying MSRP
Created a Preferred Build sheet with the dealer, for a Tacoma Sport in Bronze Oxide as first color choice.
