The element IS the resistor. I ended being able to repair the stock element, so replacing it with the "3 wire" one I purchased was not required. Since the power supplied to the element is controlled by the control switch ( 0 or 00 ) that is where any resistance to lower the voltage would be placed. I would suggest soldering the brown wire ( + lead ) to the wire that i connected to the "high" setting on the replacement element. Test it before you put the grip on. If it's acting flaky, connect both wires from the new element to the positive lead (brown, I think). Then test again.
