I bought a head unit from a guy on here, and he forgot to ship the wiring harness with it. Im sick of waiting because i have no clue why it hasn't arrived yet, so I was gonna go to circuit to get one for the CD4000 i just bought. Is there anythign I need to know, or would the wiring harness they have for eclipse at circuit city be a replacement for the one it comes with? ALso, is there a special wiring harness for each model, or is there like a standard one that fits all eclipse head unit? I don't really trust the people that work there that much.
