I'm looking for a pigtail that will connect to a factory radio, not one to adapt a factory harness to an aftermarket radio.

My radio harness was butchered 30 years ago (by me) to install an aftermarket radio. I probably threw away the plug I cut out of the harness. Now I need that plug, or something like it.

The radio I have is an AM/FM cassette, model#: 16138181
I'm planning on modding the radio to add a internal USB player and an aux input jack.

Does anyone know of a source for the plug that will fit into the back of this radio?


Also, it says "DNR AUTO LOUD" on the face. Anyone know what that is?


Thanks

 

Any car audio shop will have what you're looking for, or at least can get it.

 

The only thing I've seen is the pigtail to adapt an aftermarket radio to a factory harness. I'm looking for the opposite of that, a pigtail that will plug into the factory radio. Is that what you are referring to?

 

Yep, I know exactly what you're looking for. The same companies that make the adapters to plug onto the stock wiring also make repair harnesses for the car side.

 

I have an 87 with a factory harness in it I could cut but not sure if that's going to be the same plug configuration you're looking for.

 

OK, great!

I guess I've just encountered uninformed sales people so far.
Perhaps I can find it online somewhere as well.

Thanks!

 

I would have to get a picture of the back of my radio and compare it to a picture of your harness. But if I can find one that is supposed to fit that might be better than butchering your harness.

 

It seems that it is all in how you search. When I Googled "repair harness" I got a Toyota "Reverse Wiring Harness". So I tried "Reverse Harness" with the radio model # and this popped up.

"Metra 71-1858 Reverse Wiring Harness for Select 88- 05 GM Vehicles"

It looks like it will fit and Amazon has it for <$10.00.

Thanks Six_Shooter!

P.S.
While the 71-1858 fits my radio, it does not have all possible wires.
Metra makes another harness:
71-1858-1
I think that this harness has the extra wires mentioned in posts 18-21.

 

"DNR" stands for "Dolby Noise Reduction" and it should be "AUTO LOAD" meaning the minute you put a tape into it , it starts playing (as opposed to having a separate "PLAY" button needing to be pushed to start the tape)

 

Dolby Noise Reduction? I'd forgotten all about that. It's been a long time since I used a cassette tape. Thanks.

But is says very clearly "AUTO LOUD" (I'm not yelling, it is all caps on the radio).
I wonder if it could be a speed sensitive loudness mechanism. The pigtail I found only fills 3 of the 4 possible plugs in the back of the radio. The remaining has 6 or 7 wires and I wonder if it is for optional steering wheel controls of some other mechanism to make it get louder when driving.

 

Not Sure If It Will Have What You Want,But You Can Try A Search Here.

Thanks, but I already ordered the Metra pigtail. It should be here Friday, so I'll know then if I need to keep searching.

 

If it does say AUTO LOUD (and yea , I knew you weren't yelling ) you could be right about the speed sensitive radio volume but I didn't think that feature existed on our cars ? I wonder if "AUTO LOUD DNR" could have been the fancy name given to the Dolby noise reduction system by GM when they licensed it's use ? I went out to my car to try to solve the mystery , since I recalled my radio mentioning something about Dolby , and son of a gun if it don't say "AUTO DNR" with no mention of "LOUD" . I'll bet GM tweaked the labels somewhat through the years and of course I have no way of knowing if my radio is original to my car or not . It would be interesting to see photos of the radio faces down through the years 82/92 , that's for sure .

 

I know that this radio is not original. It came out of a friends lake 80's Chevy pickup. He donated it to "the cause."

I'll try to get a picture...

 

I do the same thing with my car , in that I use GM parts that fit regardless of whether they are "correct" year or brand wise . For instance , my tail lights are from the early third gen with the slotted look , since to me those are the classic firebird tail lights . The ones that are year correct for my car are in my opinion butt ugly , and so got replaced . Same for the interior , my car being a base model didn't have the split rear seat like the trans am does . Well one home brew bracket later , and my car has the seat I wanted it to have .

I have been taken to task for not sticking to specifically 1989 parts , but ya know what ? At my age , ain't too many of MY parts are original equipment either

 

All of the factory GM harnesses I've worked with from this era seem to be missing that fourth connector. I think you might be in to something with the steering wheel controls idea. I'd be interested to see if one of the members here with a thirdgen that has the steering wheel controls could chime in on this after checking their harness.

 

Completely agree with you! I swapped out the grid taillights for the earlier ones with the horizontal dividing line and swapped the hood for the earlier IROC/Z28 hood with the louvers for the same reason. It's my car, so I'm building it with the parts I like best. Being that it was originally a base V6 RS and wrecked when I bought it just made the decision easier.

 

Yes, the 4th connector is for additional functions.

 

Mine is an '82 SC with '92 ground effects and an 82 Z-28 hood, and I like it that way!

I wonder if I can find out what they do? I think some tinkering may be in order...

 

Steering wheel controls, VSS (for speed dependent volume), external cassette/CD player, and I think that's it.

 

External CD player?

I've read someplace that you can get a pigtail for that and use it for an AUX input, without having to open up the box. I'll look into that!

Thanks.

 

If you find anything, let us know. I for one would be really interested in that

 

Nothing yet on the extra connections.
But the Power/speaker harness I got fits the radio and seems to work. It powers up and changes channels etc. I don't have any cassette tapes anymore and without an antenna it will not pick up any radio stations. I got an antenna, brought it home and noticed that the Delco radio does not have a standard size antenna connection like all aftermarket radios and older GM radios used to have.

Lot of places sell the adapter to go from an aftermarket radio to a factory antenna, but the other way, from an aftermarket antenna to a Delco radio is harder to find. I think this is the right part:

METRA Ltd 40-GM20 Gm Radio Antenna with Mini Adapter

The reviews on amazon are mostly people installing aftermarket radios, complaining that it isn't the right part. The questions on Amazon all have contradicting answers. But I'm pretty sure it is what I need.

Once I get an antenna hooked up and make sure that the radio actually makes sound, I'll report back.

 

It turns out that Metra makes another harness that includes the extra 6 wires:

71-1858-1

I think that this harness has the extra wires mentioned in posts 18-21.
