Replacing the radio back to period correct with a 1989-94 Pontiac radio. I got the harness all wired up.

Three questions;
1- car's antenna wont fit in back of radio now. What adapter is needed?
2- Any idea why the LED blue display doesn't work? (orange wire to orange, right?)

3- What is the black (grey) connector? coming out of dash? See pic

Connector is battery power to radio memory and lighting.
There's a pigtail on the radio that plugs into it.

Thanks except my radio is a 1989-94 Pontiac radio and doesn't have the same connectors. But now at least I know the plugs functions. Thanks. Steve

Buy the harness for the 1989-94 Pontiac radio from replacementradios.com. It's prewired and the plugs from the Fiero wiring harness plug into it and it plugs into the 1989-94 Pontiac radio. No cutting or splicing. Well worth the money, IMO. I used it in both of my cars when I installed Monsoons in them.

IIRC, there was a 90 degree adapter installed from the factory.

Replacement Radios has the 90 degree antenna adapter, too. It came with the harness

This is the wiring adapter you will need. Plug and Play.

Thanks but as the OP says I have a 89-94 Pontiac radio that has a different harness, its not a "Fiero radio". The harness Im using is this one:
https://www.amazon.com/dp/B...dt_b_product_details

Its all connected and works fine. My question was about the display light.
As for the connector shown its integrated into the newer style harness. Thanks for that heads up.

The adapter I linked is for GM 89 and up radios installed in 88 and prior vehicles. It's a no-splice harness. The factory harness plugs into one end, the other end plugs into the radio and it includes the harness for the memory and illuminaton.

Since I cant see the other end in your pic in the link, I doubt it would have worked. I have a 21 pin connector not 20 as in the listing.

Yes, your receptacle is a little different than my 2000 Grand Prix radios.

Yup I have two radios like this. Just different enough to be a problem finding the right harness.

Last night I did some searching and I also pulled one of my radios off the shelf. The difference is the upper right socket area of your image. My radios have 6 pins, yours has 7. Also, that socket is somewhat elevated on yours and is on the same level as the left socket on mine. I searched Replacement Radios for gm 21 pin and came up with the same harness I suggested and in the description, it said it was a 20 pin, sometimes called a 21 pin. But it doesn't match your sockets.

Not knowing what specific vehicle your radio came from, I went to Crutchfield.com and entered 21 pin adapter. 1990 Grand Am Coupe. This is what I came up with, but it won't work, either. https://www.crutchfield.com...Harness.html?tp=2977

May be that the only way to get the correct harness is cut one from a junk yard find.

You may be able to get a connector for your radio from the Junk yard, and then the adapter harness and splice the two together to create your own specialized adapter harness- so you don't have to cut up/modify your car's harness.

Typically, the adapter kit would only have the six pin connector for the power, and then the two four pin connectors for the speakers. The seven pin (or six) is for external tape decks or CD players. They're all the same from like '89 to '02 across lines for swapping purposes if you're just using the head and no auxiliaries.

Notice how that kit in the amazon link only has the bottom connector and then one four pin connector for the top row. Thought if you're saying everything is in and fine without that lighting connector, I'm not sure how you have it wired up.
