Car Stereos: wiring diagram, lr brown, brown ant

Question
I have a Delco AM/FM radio from an 1984 Chevrolet pick up truck. The tag on the side has the following info:
Service Reference number: 40BCMS1
Part Number: 16009960
Return Number: 995992
Serial number: 1516795
There is a place in the back where it is obviously meant to accept a multi wire plug.  There are 6 wires that come out of the right side of the radio, 2 white, and 1 each blue, orange, grey, and green. These wires go around to the back of the unit near where it looks like the plug should go in.

Inscribed in the casing is:
+RR   RR-
+LR   LR-
+LF   LF-
+RF   RF-
LAMP  ANT
GRD   12 V+
The problem is this inscription is not near the plug so I'm not sure how that is oriented.

I'm planning on installing this radio in another vehicle, but I need to know how to hook it up. I can see the wires attached to the connection in the radio, so I may be able to make up a connector if I know what color/function combinations are.


Answer
Harold,

Sounds like a basket case.  I would look for another one with wires and plugs intact.  I did find a GM wiring diagram and will paste it below.  I hope it has what you need.  -Scott
