No power to anything

[CHARGER1352]

so i bought a 2000 rx 951 about 2 months ago with a bad rod bearing. so i replaced the motor got everything hooked up and come to find out nothing has power? i have the positive cable on the starter the neg in the hole right next to it. i also checked all the fuses and they are all good what could be doing this. i thought there was another ground cable hooked up to the front of the motor by the oil pump but dont see any wires? thankyou!!

Theres the main line that goes to the starter, and theres probably another smaller red wire that will need to be hooked up to the battery.
