I am currently attending and automotive coarse.

I am currently attending and automotive coarse and, I have a 2002 Ford Taurus 3.0l non overhead cam. It my car that was given to me for graduation. I drove it one day and I was loosing power on the freeway, I pulled off the freeway, opened to hood and steam was present and steam through the water radiator cap, with no water in it. After trouble shooting, I found out the head gasket had blew and was loosing compression in cylinder 3. I had replaced the head gasket and put the engine back together, tried to turn it over but there is no ignition, and no initiation of the start. Not to mention that isn't my only electrical issue, when the key was put into the ignition, and is turn to the on position the cluster lights do not work, along with the radio, and the windows. But the first time I tried to turn on the car after repair the head gasket all the lights worked, the radio and the windows worked too, I tried to crank and no response from the starter, and all the lights turn off and never cam back on after several try's to turn over the car, each time no response. So what I'm asking is what errors does it look like that I have made and if possible a easy to read diagram of all the electrical connection in the engine compartment, because I know I connected them wrong in some way.
