You mean the 102 pin connector under the windscreen pillar? Make sure you find the right wires as there are different wire with the same colours that do different things!! Rear Speakers are Pins 1, 2, 3, 4. Same colour wires as at the back.

There's also connector H8-10. On the right hand side D pillar near the side window.
Wires are
RH Speaker: White (+) Black/Blue (-)
LH Speaker: Green (+) Black/Green (-)
