hey guys

im having major issues with my fan not turning off.

i bought my car and the previous owner did some rewireing, im guessing he did it wrong because the plug in front/right of battery is burned causing my headlights to go on and off just by starting my car,

they way hes wired it the fan runs non stop which overheats the plug/wires. but i have no idea how to hook it up right because i cant find the origianl plug to replace it with.

anyone know about the wiring that could help me out? also theres no on/off switch not sure if its supposed to be or not. if anyone could walk me through the colors and what they do/ or offer any advice i would really appreciate it.

btw its a 85 z28
