I've got a Delco/GM Radio I'd like to wire up an use in my shop. I found but it does NOT come with instructions to tell one which wire goes here, to what or from what. As well they have pig tail leads to every one of 24 pins and my most basic radio (DELCO PN 15766185 CI: DCSL SER MAN 3 *89DCSLM222735248*) likely uses just those to power, illumination and speakers.
The vendor selling the correct connector for twenty dollars writes "
Identification
of the wires in your vehicle, as well as pin location of those wires in
the plug, will be up to you. Yes, research will be required and it may
be challenging. GM did not use the same wires for all the vehicles that
had this plug, so we cannot provide one plug that is going to have
easy-to-determine wire functions for all vehicles.
"
So, my question "Does anyone know how/where I might be able to get the pin out for the connector on this radio?"? Preferably at no cost :)

Try looking at upfitter manuals.
This one is for 2012 Pickups. Look at C-63.
Depending on year, features, etc, the radio can have *many* iterations incl CAN being required. Knowing the donor vehicle and RPO codes helps tremendously.
If the radio is one of the CAN-required variety, it will want/need to connect with a Body ECM. Usually associated with Bose Audio (9 speakers). Further, if it is Bose, and amplifier is not present and feedback from Body ECM not available it may go into a security mode requiring installation into donor again to retrieve 'replacement / swap' code.

So, my question "Does anyone know how/where I might be able to get the pin
out for the connector on this radio?" Preferably at no cost :) I wish you luck with that... Mostly because Delco. Back when I was repairing a lot of stuff I would often go and visit a friend who worked at a much larger repair business. They did factory service for Delco, which required a fairly hefty investment in some specialized equipment. And what he told me was that they were *very* proprietary about their information, and that if any of it got out, they could lose their authorization and their investment in all of that specialized stuff. They were a fairly large business, and the Delco stuff constituted a nontrivial portion of that business. I have a car radio here, and attached to it is a little FM booster, that used to hang under the dash of one particular vehicle. In addition to power there's wiring for four speakers, and in some cses (not sure about this particular radio) there will be wiring for lighting, separate from radio power because it'll be dimmable along with the rest of the dash lighting. I'm in no particular hurry to try and do anything with it as the AGM battery that I have here that I was planning to use for my ham radio stuff has apparently decided to go to sleep, pretty much permanently. Then there's a need to get an antenna for it, not all that much, but still something I'd have to go and get. Best thing I can suggest is to try and trace stuff out, and see which wire goes where. This will be complicated by the fact that there may be two separate wires for any given speaker, due to the power amplifier being in a BTL configuration, as in no common ground connection. One possible source for wiring info is Haynes manuals, typically available at Autozone. Pretty many of those have wiring diagrams in the back. If you know what vehicle used that radio you could probably go in there and look at one of those manuals, see if it has the info you need. It'd save you a bunch of timek for sure. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.

Why the heck would CAN be required for a radio? Sounds to me like typical overcomplicating things. If the radio is one of the CAN-required variety, it will want/need to connect with a Body ECM.

Our 2001 Volvo S60 has volume up/down and tune up/down (maybe change from to AM/FM) on the steering wheel.
It uses the CAN buss to pass commands to the radio.
?
There was a CD bay 10 that also used the CAN Buss, it had "issues" that would randomly jam the CAN buss, ripped it out and problem solved.
?
The window up/down is controlled by the CAN buss, as is the door lock, security system [which dies when the nicad pack under the right front wheel rain shield dies, which also stops the sun roof.
?
The can buss controls almost everything in modern cars and maybe everything.
Our Echo being a basic car doesn't have a CAN buss and I love it!!!!!
?
I hate CAN et al almost as much as the NEC lock down our rules.
?
|
OK you don't like CAN BUSS.?
What about sources for the information (PIN OUT DATA) requested??
|
What year, make, model car did the radio come from?
Is the Delco part number for the radio in question?
Did the car have a CD stack player?
Was the antenna in the windshield or motorized?
?

Why would CAN be required? Many reasons, a few being:
Navigation, speed correlation, settings customization, satellite radio control, onstar interoperability, split sources between seats, play movies to front verifying not in gear and speed zero, play movies to rear, data bus to CD changer, data bus to map
Disk drive, theft prevention, communicate to body / engine ecu for power requirements, amplifier setup & config for occupancy, dim lighting, environmental controls, and so on.
Use the upfitter manuals for year and model type of donor, heck even build date of radio plus a year or two. You will have your pinout. If have RPO codes (in glove box), then search for those plus upfitter manual.
You could also maybe call GM and ask nicely. Stealerships may help as well.
CAN isn't all bad, though does get highly annoying.

- No idea, immaterial
- Part Number is declared in the OP
- No idea, immaterial
- No idea, immaterial
First of all, I appreciate the interest and only wish someone knew how to proceed.
?
As to the CAN and the vehicle the unit was extracted from, the part number(s) on the label (recited in the OP) should tell us its capabilities or lack thereof.? It has but two connections apparent. The 24 pin mentioned and the female co-axial antenna socket.?
?
It is devoid of a tape deck.? It was likely the bottom of the line, basic radio bereft of such accoutrements to be found on the sound systems in a high end, well-equipped vehicle.
?
The question is How can one get information on a Delco radio using the numbers/information printed on the unit's label.
?
If it is one of those units devoid of an amplifier, or otherwise dependent upon an external component, surely the model number would be sufficient to establish such fact.?
?
Why does it appear 'everyone' is focusing on why the radio might be like the one their brother's uncle's neighbor had instead of the one in hand and identified in the OP?
?
If one's answer boils down to "I don't know," why bother taking time and making the effort to respond in the first place?
?
For the record I linked to the page that contained a partial list of GM/DELCO radio part numbers known to employ the same 24 pin connector (a page that also includes a plethora of models these radios have been 'factory' installed in. ?
?
However the ONLY thing that we need to know is how this particular GM/DELCO radio works.? It matters not if one appreciates CAN or cannot appreciate CAN if this particular radio was installed prior to the use of CAN, or did not connect to a CAN (because it was a basic radio with amplifier that connected to just two speakers in the dash - for instance).?
?
KISS Principle.? If you don't know, remain silent.? If you know how to look up GM/DELCO radios by part number, well then, post a link (Please).
?
If you want to talk about CAN, great. Simply change the subject line appropriately and run with it.
?

None of the radio Connectors shown (last few pages of that pdf_were even close to a match fro the 24 pin connector linked to in the OP ( https://www.ebay.com/itm/372448612009?gQT=1 ?)
?
This thing could have come out of a GM vehicle.? Regardless the objective is to trace the radio's PN
?
FOR WHAT IT IS WORTH the label lists QC checks for URT, BURN-IN, CUST. CHECK, EEPROM, VISUAL & AUDIT It was assembled after NAFTA? Because it was "Assembled in Mexico."
?
?
?
?
|
Sorry if my response was less then helpful, the "URT, burn in" on the label suggests the radio has network capabilities.
?
I requested year, make, model because it is often possible to track pinout information that way much easier then with an in house part number.
?
The Delco part number didn't show up in any net search I attempted, just like with my Toyota part number.
?
The part number on my Echo's radio is apparently Toyota's in house part number number used for inventory tracking and I never could find any information using that number, however knowing the year, make and model returned several accurate wiring diagrams with the available options, it was then easy to pick the wiring diagram that applies to my radio and hence the type radio and pinouts.
?
I wish you the best of luck and will refrain from responding to anymore of your requests for information to save you the angst of logical and lateral thinking.
?
BTW URT almost certainly is short for UART. I'll leave researching what a UART is up to you.
?
Oh, you can get an approximate age by opening the radio and reading the date code off the integrated circuits. I also leave that bit of research up to you. As an educated guess, I'd say over 90% of ICs have the date code in a standard format, an IC date code gives you the earliest possible date of manufacture. The date codes of several ICs should narrow the possible DOM to a year or so.
?
Oh, DOM is trade slang for Date Of Manufacture.
?
Again, good luck and sorry for wasting your time.

Several years ago I was able to get a simple car antenna from my local electronics wholesaler, cost around $6-7 or so. I'd tell people that they had to get their mechanic to drill the hole in the fender and route that wire, and I'd plug it in and they'd get much better reception. These days both of my vehicles have those really short (under 6"?) antennas mounted on the roof near the rear of the vehicle.

Actually, most manufacturers will have a version or another.
I believe the idea was started when RV manufacturers started using roling chassis vs custom frames. That was back in late 60s.
Or could have become routine when I am enforcement became irritated enough when converting passenger vehicles.
Now, near every chassis, cars included, that has room for extra 'stuff' has something available that aftermarket uses. Ford & GM are extensive, as is Mopar, for van and pickup.
