you will need the Glow plug harness. and possibly the glow plug. Chances are it is in your harness. you can find them on amazon or your local dealer. Some people like using the removal tool but if you are replacing the harness then it is not a big deal.

I would pull the connector off the GPCM and check the #3 pin to see if you get an ohm reading before attempting to replace the glow plugs.
I learned this lesson when I got an error code for #8 and jumped ahead replacing it but it wasn't the glow plug. It was my GPCM that went bad.
I was told that glow plug rarely ever goes bad.
You can read my post at https://www.ford-trucks.com/forums/1...rror-code.html it have the information in it about measuring ohms from the connector and connector diagram.
