Read this thread for help on the main headlight harness:

Also, regarding the signals, use your existing bulbs and sockets, not the new ones. There could be a difference in the socket that might blow a fuse (it happened to me quite a few times).

Lastly, that triangular socket is nothing crucially important to making your lights work. It is for the headlight leveler switch, which allows you to adjust your headlights from a switch inside your car (normally beside where your fog light switch is). Your lights will still operate perfectly fine without that function, because it is its own self contained feature.
