I am working on installing a after market deck in a 2004 toyota 4-runner and it has the jbl synthesis pre amped system in it and I am looking for the amp wiring for that system so i can get sound out of my after market deck. In specific i need the amp turn on lead wire colour, but any help in this area would be greatly appreciated, or does anyone know where I can get a hold of a NC-TA10T amplifier interface. Thanks in advance.

Do you have a retailer of Scosche or Metra in your area?

If not, then I'm sure that you can have one shipped to you quickly.
