Ha ok, Well now that you mention it i had to pull the pioneer harness apart that was in it as the speaker wiring was all mixed up, Instead of having the pioneer wiring like white & white is front left they had it so they were using one white and one other color (can't remember as i just pulled it all apart) as if to bridge it, It might be that they had a non pioneer head unit and the wire outputs are different as i know some harnesses are interchangable but its all fixed.
