Here's a good one for the Expert,

Can someone help me identifies the 16 wires color code of my 99 deville Delco Radio-Cd player.

I want to install my Head Unit and the 7 speakers I tooked off from my 1999 deville (salvaged) and connect it in my 1989 Eldorado. Hoping that I have'nt left anything behind ?

I already have custom installed the Radio-Cd and the speakers :

2 6x9 for the back
2 5 inches and 2 tweeter for the front doors
1 3x5 for the dash

See the pictures of the connections and the Head Unit of the the 99 deville
and also the 4 connectors of the 1989 Eldorado

Here are 16 wires I would like to Identify

Top row :

Re: Here's a good one for the ExpertDelco radio color code Identification NEEDED !

sorry to have to tell you - but - it's not going to work -

that radio has THEFT LOCK -

a system that checks and verifies the VIN number stored in the radio
matches the VIN of the car it's installed into -

if those VIN numbers don't match - the radio locks itself -
and becomes totally useless -

the dealer then has to "flash" the radio to erase the old VIN -
and when plugged in - and turned on for the first time -
the radio will store the new VIN -

and here is where the problem is -

your 89 Eldo will NOT report the VIN to the radio -
it just isn't wired that way - so the radio will never work -

Thanks basscatt, I did not see that one coming ....


What do you suggest ?

Rewire the radio with new independant wires after the dealer 'Flash', so the computer will not know ?

Or keep the speakers and install a different HU ?

Any suggestions ?

maybe I wasn't clear -

that radio from your 99 Deville will not work in your 89 Eldo -
the radio has THEFT LOCK - and will not play -

You can't install that HU in the OBDI car.
At least is not as easy as you would imagine.

You need to pull the DIM form the donor car, you need the HU pictured, you need the amplifier.
The HU communicates with the DIM (on the data line E6,F6 pink wires) and requests the VIN (for Theftlock reasons). Having the ACTUAL dim from the same car with the HU will solve the issue of clearing the VIN at the dealer (as the 2 modules are paired).
So you need to connect the audio wires between the HU and AMP, the data wires between HU, DIM and AMP.
You need to run the power wires to the modules (the proper power source, not straight from battery, some need to be ignition key controlled). The DIM especially has few power inputs (to know when the ignition is on, what position). Bellow is the diagram of the BOSE sound system (far more than just a HU in the dash). I missed from it the DIM, it suppose to connect on the data line with the other modules pictured.


Well I will end up writing for 2h what you need to do, bottom line is doable but you don't know what you are getting into so unless you have an engineering degree in electrical/electronics field and the FSM I would say to forget about it, highly incompatible systems, many things involved that you are not aware of.

Just by starting talking about wire colors is the wrong approach, in this world the wires are irrelevant (can change slightly from year to year), we are talking pin numbers.

franky, I've been talking, texting, bloggging, hell I'm not sure of the terminology about a similar swap. MC and N* have helped immensely. Somehow our topics got intertwined, thus I checked your swai out thinking it might be useful. But we are a decade off!

Thanks MC for your help and patience in that matter.

I need your guidance to make sure I am heading the right way.

I want to install a kenwood DPX500BT
2DIN USB/CD Receiver with Built-in Bluetooth
and connect it with the adapter that fit my 89 eldo radio factory connection.

www.kenwood.ca/Car_Entertainment/CD_Receivers/DPX500BT

I will keep the speakers from my 99 deville. :
2 6x9 for the back
2 5 inches and tweeters for the doors,
and skip the 3x5 that was on the dasboard of my old 99 deville

Can I connect the new Radio and the Deville speakers to the existing wires or should I run new speakers wires.

By the way I just bought a used Factory Service Manual from Ebay. 25$ delivered in Canada. Great help !

Big Thanks

Installing an after market head unit is no problem. Installing different speakers is.

The factory speakers in your car each have their own built in amplifier. With the system wired as is, without those amplifiers, there's no sound.

Buy the adapter for the HU, and use it to get power to it, but you'll need to run your own speaker wires.

The other problems with using the Deville speakers are, one - they're designed to be amplified, and two - they're a very low impedance.

If you really want different/better speakers, buy after market ones that are designed to work within the power range of the new HU.

Well, Thanks a lot MC,

It is very nice of you to answer all my silly question...

I have learned my lesson well , and next time I do a move of anykind, I will ask first.

Have a great day :duck:
