Don't know how the 5 speed is different from the 6 speed. When I did mine, I need to add the reverse light switch connector since it was absent on the 5 speed auto but the switch is on the 6 speed gear box. The connector is a generic Bosch two prong connector. I made use of one I pulled from a 94 SAAB 9000 I parted a few years ago.
The green and blue wires go to the reverse light switch on the gear box, if I remember correctly.
