Another method for those without ramps or a hoist. If you remove the entire air intake system back to the throttle body (only another 2 bolts) you can drop a 30cm 10mm extension (or T-bar) straight down onto the single 7mm bolt on the back of the pack. Standing in front of the car, reach under the manifold with your right hand and push the leads off then twist the pack 90 degrees and pull it out between the bottom of the manifold and the heater hose. If you mark the top of the new leads with the plug number either on a white sticker or with one of those silver paint "texta" style pens then you can put the new pack in the same way, get a nice bright light shining in the right place and peer down between the edge of the rocker cover and the manifold and push the leads home in the proper order. Bit fiddly the first time you do it, but quick after that as you know where your hands need to go. Takes about 20-30 minutes all up. Wear a long shirt though as otherwise you'll rip the skin on your arms to shreds...

(You can also just push the old pack out onto the ground and drop some heavy string down the gap you used to undo the rear bolt, tie it around the new pack and pull it up, then cut the string once you've got the pack into the general position. Have done it both ways but my AUII may have a bit more slack in the heater hose and it will come out via the top.)
