1. Remove the rear bench seat.
2. Pry up the carpet in the rear of the van.
3. Locate the wire harness, which will be taped to the floor.
The wire harness will have four wires: two for the positive speaker terminals, and two for the negative speaker terminals. The positive wires will be marked with a "+", and the negative wires will be marked with a "-".
To connect the speakers, simply match the positive wire from the speaker to the positive wire from the wire harness, and the negative wire from the speaker to the negative wire from the wire harness.
