What year is your truck? Last summer I replaced my factory AM only radio in my 78 with a Retro Sound unit.

Here is a pic of the back of the original AM radio.
On the right side is where the connector goes. It has the following wires
Ignition Switch
Wire to light switch (light in the radio that comes on with dash lights)
Ground
And then speaker wires.

The circular connector on the bottom left is for the antenna.

I do not have a pick of the wire connectors themselves, just the back of the radio.
