What is minimum electrical required to start my car?

ok here are the pics NOW just from pics no way you cn figure out the problem ... I know most will say rightthere is the problem the rats nest for wiring... NO ****!!!! why u think I want to eliminate all that JUST TO GET FIRE.... believe it or not nephew had it much much worse... some of his handy work is still visible, like the plastic see thru connectors... the wiring is in most places temporarily hooked up, once it all checks out will make it permanent/..... I DO NOT NEED LECTURED ON THE WIRING... I ONLY ASKED FOR HELP AVOIDING THE WIRING TO JUST GET IT TO GET FIRE SO I KNOW THE MOTOR WILL FIRE UP....IT HAS NO FIRE... i used a 74 dart wiring diagram to "try" and it all run correctly to where it is supposed to go to... but that wiring diagram was not correct for the voltage rugulator and made a pile of wires like 6-8 goto same place..... also for ya folks that didnt get it before... the car does not turn over by the key(it did before removing the battery one night and installing it back the next morning but not now) I can jump across the relay to get it to turn over... ok here goes gonna post pics... very frustrated and not in good mood so PLEASE dont tell me the very obvious about the wiring... like I said, just want it to fire up WITHOUT the wiring AND GO FROM THAT POINT FORWARD
