I took out my trunk carpet to clean it last week. I noticed a pair of unused connectors on the left rear under the carpet. One looks like a 13-pin changer connector and the other is maybe a 6 conductor power or speaker connector, taped together with the antenna control wire and clearly never used. The car is a stock 2000 x, so this is not aftermarket. It has the stock changer mounted on the right, but as it skips so much, i am looking at options. Does anyone know what the connectors on the left rear are for? Dan
