hey guys looked for a bit, im in a rush so im posting here well i continue to look,

i need a wire harness for a ls b18b , im having troubles with my rad fan not comming on i have a feeling it has to do with wires so if anyone can get me a harness diagram that be perfect!

 

did you try jumping the switch? its the 2 pin connector at the thermostat housing. if you jump it and the fan engages, switch, or connection to switch is bad
