Problem with 2003 Lincoln LS with THX sound system

[HotRodHam]

so im trying to install a aftermarket cd player in my friends 03 lincoln ls. it has the thx sound system in it so no company makes any wire harnesses for it. i was wondering how would i connect the factory amps to the aftermarket h/u. (he wants to keep the amps)

here's a wire diagram.

original thread if u can't read it. ( http://www.lincolnvs...&highlight=avic )

i would like to find a way to do it without using the h/u's rcas

and the amp (enables) are the remotes for the factory amps i take it?

if anything else ive been searching bout an hour now for a headunit wire diagram since i just realised this one i posted doesnt have power, ground n so forth.

any info will help at this point XD thanks in advanced

E/ just realised thats a diagram for an 04 anyways -.- i rilly need help finding that wire diagram lol
