ezgo marathon wiring

I bought a rolling 1993 EZGO Marathon 36v with only a motor. I have gotten everything else for it to run but I can't figure out what wiring harness I need. Could anyone help?

Hey so I think I either need a new speed controller or I wired the new solenoid wrong. When the key is in one position the cart works perfectly but when I turn the switch in the opposite position the cart just takes off without anyone pressing the accelerator which means I can't turn the cart...
