    Wink Re: Stereo swap from 96 SLS to 99 Eldorado + my findings after 8 hrs.

    Today, I found a Pick-n-Pull yard south of Seattle in Lakewood. the attendant gave us directions in the yard to a 95 & 97 Seville. I found the 97 with HU intact. Wow this was to easy! I thought! I couldn't move it from Park to 1st. Which in turn made removing the shifter knob difficult. As well, the ashtray didn't want to come out, so I checked out the 95. There was a guy pulling the rear passenger brake drum and his girl was checking the dash out, as I walked up and said Hi!, she shut the driver's door and stepped away. It didn't have 1/2 the dash, let alone a HU! So my GF and I went back to the 97. I haven't been to PnP yard since 85 or 86, so I felt a little out of my element, but what I went back to the 97 qnd sat in the driver's seat, and what I have been needing and wanting is staring me in the face! I thought to myself, #1 I like puzzles, and removing this is just another puzzle. ( I wrote about my puzzle affliction in a reply to RKeating a week or two ago.) #2 I have taken classes @ CFU ( CadillacForumUniversity)! Thanks to Professor N* and MC. I was able to remove the shifter knob while it was in the park position. I then had to twist and turn to remove the trim around the shifter. Once that was removed I could unscrew 2 screws. BUT, it's not coming out unless I can unscrew the screw which is under the ashtray. So I commenced twisting and turning the ashtray, and low and behold, it came out intact! I unscrewed that screw and the other two. I then pried the top faceplate off without breaking it and got to the top two screws. I removed the HU and temp. control unit. We proceeded back to the cashier and stood in line. It seemed to be busy, as they brought in another cashier. Finally, it's my turn, he rang up a stereo for $14.99. I paid him and when he was writing a # on the head unit, he asked me if I needed this part. I'm not sure what part he was pointing to, BUT, before I could answer, the guy next in line made one of those AHUMB noises, and the cashier said, something like, Oh well, and went to wait on the AHUMB guy. So in closing this chapter, I think I earned an A from Prof's. N* and MC, in ther Cadillac 101 class! and a special TY to all who helped me study. I have what I need and didn't break anything on the donor car! Did I say that we found documentaion that the 97 was built on 7-17-96! I believe this is a simple plug and play deal now. More to come...............

    Having written that, I must say I messed up today. I obvisiously encountered another Cadillac owner, who like most of us or all of us, love them enough to DIY it. I should have introduced myself and I may have recruited a new member!

    Re: Stereo swap from 96 SLS to 99 Eldorado + my findings after 8 hrs.

    This was supposed to plug and play, haha on me. I should have taken this apart before I went to the pick-n-pull. Then I would have known I would need the male end of the 32 pin plug. The previous owner made a real mess of things IMO. I've got to back to Seattle in another week, so I guess I'll go back and cut off what I need from the pnp donor car, and splice it back to what it once was. Or does anyone have a better suggestion.a wiring mess 002.jpga wiring mess 003.jpg

    Can't make it any worse...
    Time for some soldering and heat shrink. An hr or so & you'll have it bullet proof again.

    Re: Stereo swap from 96 SLS to 99 Eldorado + my findings after 8 hrs.

    Thanks for that suggestion rodnok! It has been easily,(or is it, easily been) 20 yrs since I've installed a stereo in a car. Back then you needed a grd and a hot wire and 2-4 speaker wires! Having read everything I have to this point, I knew how much things have changed. I've used heat shrink many times, but in other applications. I quite honestly hadn't thought of it as something on my list of needs. Soldering yes, but I might as go buy a new one. As it would take me 3-4 hours to find the one I haven't used in 10 years. I'm a hoarder wannabe!!!!! Here's a couple of pic's of the Caddy's and you might see a MGB in there as well as a 1963 all original restored golf cart!CFU 002.jpgCFU 005.jpg

    Oh my God, idiots should not be allowed to work on cars, why would you do something like that on your own car?
    Soldering should be fairly easy, you do need the 32 pin connector with a 10 inch harness section attached.
    The easiest way is pull the wires out of the plastic connector (label the wires with the pin number E/F 1 to 16), solder one by one, heat shrink and wrap in electrical tape (the factory was using gray 1" tape).
    Then insert the pins back in the connector and you got it back to original.
    My great grandmother had a saying: "it takes one stupid person to throw a rock in the river and 10 smart people to find it".

    Get the harness from a '96+ NON Bose vehicle so you have color matching wires.

    This is how you remove the wires from the connector:

    The donor car was a 97 SLS non-bose. I'm hoping the needed part will still be there. Thanks for more helpful advice N*.

    Eldo 003.jpgEldo 005.jpgEldo 001.jpgEldo 002.jpgToday, I had time to start the rewiring of the HU. But before I got started, I noticed the 32 pin connector didn't have 32 wires in it. I kind of expected it to, but I'm not sure. This 32 pin connector came out of the same car as I got the HU from, so I think it should work. I count 11 blanks in the connector thus 21 wires. I could pull the aftermarket out and start, but if I'm missing wires, it would create another problem. Or if there are more wires in the dash than the plug, another problem. This car is my daily driver and I need to get this done tomorrow as we are going on a 4 week road trip! Thanks in advance!

    Not all pins are used.
    Get heat shrink (about 1 foot), a good soldering gun and some electrical tape to wrap the wires once done.

    That sounds about right actually, don't remember many more than that going to aftermarket HU.

    Re: Stereo swap from 96 SLS to 99 Eldorado + my findings after 8 hrs.

    Sorry to revive this old thread, I have an STS with bose and SLS base sound system. I wanted to move the speakers and head unit over to the SLS but from what I'm reading and understanding its not just the HU and Speakers but the Comm. Bus also that leads to the daunting task of upgrading, putting aside the vin relearn requirement. IS that correct? If so Damn, I blew the motor in the STS and didn't want to scrap it with the perfect Sound System.
