NOS 1989 Beretta Radio ? Say What ?

[lakeroadster]

Any GM wiring wizards here?

I have a NOS 1989 Beretta radio that I am going to install into the console of my '65 truck. It was a dealer take out I bought back in 1990.

I am wanting to bench test it. Back when I bought it I purchased a Delco plug for it (0211A8 1#16043490 Gr. 9.656 Connector ASM.) and the guy at the counter gave me a connector ref. sheet showing connections.

The sheet appears correct, but doesn't match what I have found on-line.

Here is how I think it is supposed to be wired:

1- Green, LF Speaker -
2- Pink, LF Speaker +
3- Yellow, RF Speaker –
4- Blue, RF Speaker +

5- Black, Ground
6- Brown, Parking Light
7- Tan, Dimming
8- White, Power Antenna
9- Red, Ignition
10- Orange, Battery

17- White w/ Blue, RR Speaker –
18- Light Blue, RR Speaker +
19- Blue w/ White, LR Speaker –
20- Yellow/Black, LR Speaker +

Look right?


The on-line wiring diagram doesn't jive with the wire colors the plug has, and the data just doesn't look right to me:

Car Radio Battery Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: Yellow
Car Radio Ground Wire: Black
Car Radio Illumination Wire: Gray
Car Stereo Dimmer Wire: Brown
Car Stereo Antenna Trigger Wire: Pink
Car Stereo Amp Trigger Wire: N/A
Car Stereo Amplifier Location: N/A
Car Audio Front Speakers Size: 4″ x 6″ Speakers
Car Audio Front Speakers Location: Dash
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Car Audio Rear Speakers Size: 6″ x 9″ Speakers
Car Audio Rear Speakers Location: Rear Deck
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Any advice will be appreciated. Just don't want to fry anything
