Factory amp is under the rear seat near spear tire...
no company makes a harness so I don't have to cut the harness coming out of the amp...
Metra, Axxess, pac didn't make any harness yet ...
is anyone aware of a company making that harness

 

Try contacting www.crutchfield.com They have a wide variety of products and excel at helping you do your own installation.
Also try the audio subforum on the CL site https://www.clublexus.com/forums/lex...lectronics-12/
Then do some searching both here and there as others have upgraded their stereo system and various models share components.
