I went to Circuit city last saturday, and the guy told me there is no harness for that application, the only thing it is to throw new wires from the aftermarket stereo to the speakers amd the AMP.
I found a harness at Walmart from SCOSCHE which was supposed to be for PREMIUM JBL SYSTEMS, FDK106 or something like that and did not fit, after I opened the box, saw a note that it says that won't work with some systems, the only difference that they have seen with the green connector which is the one not fitting, it is that is has to be a little bit smaller in order to fit the black one coming out the X.
I went to another shop and they told me that they will order a connector from LA "hoping" that this one is the one that fits my X, but they were not very confident.
I don't know what else to do, I'm reluctant to throw new wires and loosing the AMP and Subwoofer.
The X has the stereo with no antenna wire.
If that harness is not the one, then I'll stay with the cassete player and return the stereo.
Please let me hear your comments and suggestions.
