Hi I got the z110 a few weeks ago and I wanna install it to the thx soundsystem in my car but the metra factory amplifier integration harness doesn't work only the main plug fits, i need to know if someone makes a harness for this any help is appreciated thanks

Are you talking about a Lincoln LS or Lexus?

Lincoln ls with factory nav/thx Im gonna get a full Jl system in the summer but I would love to have it hooked up to the factory in the meanwhile
