Ford F350 Diesel Block Heater Cord Plug

The AC plug on my Block heater has broken wires at the plug so I can not use, Does anybody have a safe fix for this short of replaceing the whole wireing harness like the dealer wanted to sell me and install for about $300.00? I was thinking of splicing on a new plug and then sealing it up?

    So, how do I replace the plug safely?

    I know I can replace the pug but isn't keeping the elements out an issue? And is there a particular type and place to buy a replacement plug? I don't want to get shocked sometime.

    Bought and outdoor cord and cut off the male end leaving about 18" of cord attached. I then spliced the new section of cord onto the block heater cord after cutting the bad part off. I used electrical tape and heat shrink tubing over all the splices to make a clean water tight connection, still going strong after about 3 years of use.

Location of block heater cable on 05 F350 diesel

The block heater is already installed in your 6.0. The cord may not be there as it is an option in some states and standard equipment in others. The best way to see if your cord is there is to crawl under and look up by the # 4 cyl and you will either see 2 prongs sticking out for the cord or you will see the cord. The cord should end in the front bumper behind where the front tag would be. If you dont have the cord Id suggest getting it off ebay as it should be cheaper than the dealer. Hope this helps.

I need to find the engine heater plug in cord from my new-to-me 1997 F350 diesel

Look at the passenger side of the block. The rear freeze plug should have a block heater instead of a freeze plug. It'll be the rear freeze plug. If all you see is a 3 prong plug, the cord somehow got lost. I replaced on a truck very similar to yours. I got the entire assembly from NAPA. It comes with the piece that goes into the side of the block and has the cord with it so you can plug it into an AC outlet.
