Hi guys I have an e300 diesel and can't seem to lovate my block heater. Can anyone help me locate mine?

 

Yours I believe would of come with it factor installed. So it would be in place of a freeze plug on the side of the motor. It would be a 3 wire possible the wire is off. You would need to look for a male plug with threads to screw on to, and buy a plug to fit it. Hopefully it is tucked up somewhere or someone let it hang to low and it got riped off were you could splice a new plug onto. Good luck
