Does anyone have the instructions on fitting an aftermarket head unit. i have a 2005 ls and i went and got the special wiring harness and everything got it all installed and the head unit wont fit due to the six rca jacks plugged in the back of the unit. any ideas. I think i may be able to cut the rca plugs and wire them into the actual harness for the head unit but it still leaves the rca's for the subs and i think that will still interfere with the fit. doesnt go far enough in...Help plz
