I'm having some trouble replacing the HU-611 CD/casette player that came in my car with another deck I own. The DVD player I'd like to put in is a JVC KD-DV6200. The problem I am having is that all of the 99 S80 wiring harness kits I can find don't match up with what's in my car. The kits have two rectangular plugs, which correspond in size and color to two of the plugs on the back of the HU-611 radio, but the car has one rectangle and one circle plug. Is there a product I can buy to convert the black circle plug to the grey rectangle plug?

So far I have purchased the following:

and the mounting bracket.

I've attached some pics to show what I mean.

 

You need to buy an amplifier adapter. This will take the new radio's RCA connections and make it plug into the round plug(DIN cable). Either make one or buy it off Ebay. Other solution would be to bypass the amplifier by running new speaker wire to each of the speakers, good luck.

 

Well I seem to have found the right part on Ebay.

No actual stores seem to have this for sale anywhere, which is kind of weird.
