Posted January 24, 201312 yr I am in need of the wiring diagram for the inputs of the JBL amps for a 2012 Toyota FJ. I know the voltage should be well below 6volts and want to convert them to a rca plug to install and after market system while still using all the factory headunti features.This is for a friend and I do not have the FJ handy to look at things. I am preplanning and any help would be awesome!
