Hotwire a 318

can someone tell me how to Hotwire a 318 so i can run it on a stand. . Its 73 so it has mopar orange box and 2 post balast. I rebuilt it in my garage and i dont want to put it in and risk scratching my freshly painted engine bay just to watch it self destruct. Its prob fine but i have it in a cradle and id like to fire it.
Thanks
