Color code for my am/fm/cassette

[86swb]

I looked at Acex Diagrams but the colors seem to be off than what I have on my radio for my 84 truck. My colors are:

top plug= (Black) Solid black, solid red, orange with white stripe, solid blue

second plug= (White) Solid gray, gray with black stripe, solid white, white with black stripe

third plug= (Blue) Solid green, Green with black stripe, solid purple, purple with black strip

If someone could tell me where these wires go to it would greatly appreciated.

The radio is an am/fm stereo with cassette player. The radio now in truck is just am/fm stereo but does not always work so wanted to install this one and I put all new wires on rear and I put in a new cassette belt.
