Ok, 2 parts actually:

1) I ordered the one for the premium sound system even though I don't have "premium" written on the speaker grills. Please tell me I did good by doing that. I thought I read that in one of the threads I found while searching.

2) The harness has one connector on one end and plain ole wires on the other. If I read the directions right, the connector is for the amp and the wiring gets spliced by the amp, or am I backwards over here?

Thanks for your help.
