Have '87 240 DL wagon w/ stock cassette player in top position. I'm putting a JVC unit in. Have brackert and wiring harness that plugs into Volvo wiring harness but not new unit so I have to match up wires. My wife seems to have thrown out the wiring diagram with the box. And I don't think volvos colors match JVC's. The way the harness clips into volvo connector is:
Volvo: JVC:
Green (constant 12v.) // yellow
Yellow/Black stripe (switched 12v.) // red
Red (antenna) // blue
Gray w/Yellow stripe (Rr spkr +) // white
White w/ Yellow stripe (Rr spkr +) // gray
Black (ground) // black
Gray (R spkr -) // gray w/ black stripe
White (L spkr -) // white w/ black stripe

I think I found these matched on the board somewhere but not sure.

Sorry if this sounds stupid but I'm confused. The colors of the wires coming from power, spkrs, etc going into volvo harness connector and those going out of harness and into the stock stereo are different colors. Not sure which ones to go off of. Plus there is an orange and a black wire spliced into a connnector thats not connected and has a fuse break. Another yellow wire has a connector not connnected to anything. Is that for an amp?

HHEEELLLPP! Please. Thank you.
