>I think I can see what your problem is, I think your piece of sh*t red wire to the starter solenoid cant flow enough juice when its just wedged into the terminal like that, nor is it meant to be permanently connected to power - it's supposed to be connected to the ignition barrel.

only 2 wires come should off the positive terminal (3 if you have an amp but forget about that for now) there should be that big fat wire supplying power to the actual starter (the one i circled red) and the other is a thinner wire which goes straight to the fuse box.

If you turn the key to the ON position (probably not even neccessary), use something that will decently clamp the positive terminal like a jumper lead set and connect the positive terminal to the wire on the small black connector, then the starter motor should turn and then you know you've fuct up the wiring somewhere along the way. If it should not turn at all or make just a click and not turn over then your battery is dead or the starter motor is f*cked.
