got an o2 f4i, tried to wire my fan on my spare radiator, and it didnt work. i tried running it right to the batt...how do i do this..pics wud help thanx

 

Don't it still go threw the thermostat that's on the radiator??? Maybe that's why it didn't work???

 

no idea...the plug on the left side ofthe radiator has sum wires comin off it, so i cut em an attached longer wires and ran em to the batt....still didnt work

 

Two wire coming out of the fan...... one goes back to the wire harness the other goes to the thermo switch on the radiator (should be right next to the fan) side on the wire harness is the "hot" side run this to the battery. The one going to the switch on the radiator is ground.
