Best advice is to have the radio shop fit it for you as there will be difficulties with the CPU if it is fitted wrong.

SOURCE: wiring a 1990 Cadillac Deville aftermarket radio.

If you are starting with a fresh battery and it drains down overnight or ina day or so.First make sure you alternator is sufficiently charging.Then make sure all components are switched off,including any interior lights (from doors being open)and hood lights (from hood being up).Take your ground cable loose from the battery and place a 12volt test light between the cable and battery terminal.You should have no, to very dim light.If you have a bright light,then start pulling fuses out one by one.(take one out and then replace it before you remove another)When your test light goes out,see what component the fuse is for that made the test light go out.Then check that circuit or component for short.Good Luck!!!

SOURCE: 1996 cadillac DeVille. How to install turn signal

You have to pull the air bags, and steering wheel, and disassemble the anti theft plate in the column. This task may be better left to a shop, it is fairly difficult if you know what you are doing, and nearly impossible without the requried pullers....

I’m trying to install a aftermarket deck in my 2005 Cadillac Deville I can’t afford to buy harness so not matter what I do I get no sound is there a factory amp or certain trigger wire I’m not connecting

I get this question a lot - Installing aftermarket decks in this car can be a real problem.There are a fairly large number of entertainment options for this car, and the OEM wiring harness used depends on which one you have. In cases where a Bose system is installed, there is no direct connection from the radio to the speakers - just preamp lines to the Bose amplifier at the back of the car, and aftermarket installations require bypassing that amp (which can be a nightmare). To figure out what you have to do, you need the wiring diagrams for your deck and the system you are replacing - try

What cd changer will work with 96 cadillic deville

This is complicated and depends on the radio control head module in the car. Once you have figured out the option level for this (e.g. UW7 - check the options label in the car), you can check with an aftermarket audio dealer which ones may work, and where they could be installed.

If the stereo was removed, the speakers may have been removed as well. Did you check if they are there?
Also, you need to make sure the car didn't have a Bose system installed - that system adds an amp between the radio and the speakers, and if the amp is in place, your aftermarket radio can't use it (if it is there or has been removed, you will have to bypass the connectors at the amp location so the wiring at the radio can reach the speakers directly).
In any case, you need to find and look up the entertainment system option installed when the car was built, and the get a wiring diagram for that system (try
