Iroc trunk latch?

i have an '87 Iroc with the latch that pulls the hatch down. I just got down redoing the whole car and can't remember how to wire the actuator together. The piece on the gate I think gets grounded, but I have a white wire in the trunk that connects to a module and I don't know where it goes? The trunk won't latch all the way down. Any information would be greatly appreciated!
