    The original stereo sound system head unit is a necessary part of the car's serial data bus, TheftLock, and security systems.

    You need to reinstall the original wiring and connectors and head unit, get the system working again then talk to the guys at Crutchfield about the correct jumper harnesses and wiring - that retains the old head unit in the trunk to run the rest of the car.

    ======================
    there are two special harnesses/adapters that MUST be used for a successful radio swap -

    do the swap without the adapters - the car MIGHT not even start/run again -

    HOPEFULLY you didn't hack up the original harness -

    start over -
    reinstall the original radio - get everything back to "normal" -
    cross your fingers -
    clear all the DTC's that obviously have been set -
    obtain the correct adapters -
    try installing the aftermarket radio -

    Re: instal aftermarket sterio

    The car starts and drive, I did not cut the original harness,. i had a female harness that I conected to the stereo, i hope I conected everything right,
    the only thing now is that when I put the original radio back it does not work, excite the clock buttons.
    also parking break does release anymore , I have to do it manually.
    to clean all the codes could I use a simple obd II?

    our cars have a built-in scanner that will display all stored codes -
    MUCH better than MOST hand-held scanners -

    to check for DTC's - Diagnostic Trouble Codes -
    if you don't know how - go here -
    http://www.cadillacforums.com/forums...odes-dtcs.html

    post any codes you have -
    ALONG WITH THEIR DEFINITIONS -

    include whether they are C-Current or H-History -

    for code definitions - go here -
    http://www.cadillacfaq.com/faq/answers/dtccode.html


    here is a how-to video -
    https://www.youtube.com/watch?v=0PQhWmlbG_A

    ------------------------
    after checking/clearing the codes -
    if the radio and other electronic components still don't work -
    check the fuses - BOTH under the hood and under the back seat -
