I cannot figure this out for nothing. Is there a diagram of the car I can use?
Ron, that is one of the cleanest aftermarket installs I've ever seen.The best upgrade by far is putting in a aftermarket NAV/DVD radio in my 2000 Deville. Very easy to do and took about 1 hour. The harnesses I used to hook it all up would be the the PAC OS-2-GM32 and to retain all your steering wheel controls the PAC-SWI-CP2
For the main harness module we cut out some of the the side wall in the back to slide it into.Nice work. I'm fixin' to do the same in just a few minutes on my '05. Did the modules you used in the connection process fit in the compartment with the radio, or did you have to put them thru the holes in the back wall?
