What's up guys? So i have been searching these forums for a while and found some great info so decided to join. With that said i am trying to install an aftermarket deck to replace my Ls 05 THX navigation hu. The cd player would not work. So i got another hu and i would like to keep the factory amp and speakers. So i was told that there is no harness available for this installation so am i to cut the factory harness so i can splice or is there another way? Also i cant find any wiring diagrams for an 05. Im new to this any help would be greatly appreciated.
