Hello, so I baught a 1UZFE (think its a LS400) non vvti engine comolete with its wiring and ecu mangement system it also came with a small relay box which has a "start, ignition, fuel and battery wires (each marked correctly)" they did start the engine before I loaded it unfortunately I was so excited that I didnt pay attention (really cleaver I know), now when I connect it to an normal key turning ignition switch that shows where each wire should go and a place for acc (which I assume is the negative on the battery?) so I connected it and connected the positive wire of the battery to the engine (to earth it) but when I turn the ignition it only makes n "click" sound and the fuse on the relay box blows up. I feel really stupid about this I search every thing but I really dont understand the Wiring Diagrams. Please know this is my first conversion so I know little and am still learning.Any help would be great!

Thank you
