when i had electric load it was cause the engine harness ground wasnt hooked up. check to make sure theres a vacum going to the map. and the tps probably just needs to be adjusted. as far as the wireing are the plugs cut off or what? and for battery just get good thick cable since it has to travel further and get a sealed battery for your saftey.
