Mike Does Not Recommend This Product
The oil heater harness is located on the bottom of the alternator and is usually zip tied to keep it off the bottom of the unit. You may have to look under the alternator to find it. The oil heater will plug into this harness and the other end simply goes to the N1 and N2 terminals where 240 volts is present.
