I bought my 03' DMAX truck without a block heater. Does anybody know what it takes to add an OEM heater to my truck?

the plug may be in the block already, you just might need to add the cord.

I think all Dmaxs have the block heater from the factory. The cord should be on the passenger side bundled in with some other stuff.

All DMAX'S have the block heater. I think on Kennedy's web site he has a picture of where they hide it.

I checked out the Kenny's web site . The picture was very helpful. You guys were right . Thanks.
