I'm very sorry for the slow reply!
For the wiring. You can buy a loom from Holden for about 100 and something but if not this is what I done.
withy the four wires coming from my hard lid I found the wires running the hard top light. one positive and one neg. Wired them to a positive in the stock loom running to the tail lights. I most likely wont be red. Colours mean nothing with these complex looms.
the other two is the lock. Found the positive and neg of that and connected it to the fuel flap. Bobs your uncle and she should work.
