I just noticed one of the four plugs that go thru the valve cov gskets was loose, so I unplugged it and decided to inspect. I saw that 1 of the 5 prongs (the one on the end) had at one time shorted out and completely disinegrated the male prong also destroying the female one. My <font color="red">question </font>is what is each prongs function? I assume its a glow plug wire since my truck runs fine. <font color="orange">THANKS </font>

you are right, the one at each end is for the GPs. You can buy the shells and a replacement end from IHC but I don't have the #s handy.

Thanks for verifying that, I have a different harness but will have to replace valve gskt also, but no hurry truck starting fine for now.
