Plug ID help

[jtb51b]

I have a plug with two wires just behind the fuel filter on my 2000 f550 that is not connected to anything. The truck seems to run ok, but I imagine this should be plugged to something. This plug has a wire clip that would hold it clipped to its mating plug. It has a grey wire with a red stripe and a black wire with a white stripe. It is coming out of the same loom of wires that the wires running to the green plug connected to the turbo piping directly on top of the engine, behind the fuel filter. Anyone have any idea what this may be? I can snap a picture of it if it will help.

Thanks in advance for the help.

BTW, should this truck have a plug for a block heater? If so, where would it be located?

Here are a couple pics, for some reason my phone lost the best one. Go figure..

Wow 44 looks and no ideas huh? I dont see anywhere this could connect so I am just going to tape it up. Maybe its an extra? Oh well, no use worrying about it. Now if I could just get parting brake shoes to jump onto this truck I would have something! What a pain those are!

Looks like either for the ipr or the ebpv solenoid. I think those two are very similar if I recall correctly.

Pardon my ignorance, but what are these two items? I assume IPR is injector pump relay? what is EBPV? I will search but sometimes the search function does not work with short words.

Thanks,

ok, after some reading I see that this could be a problem. This truck starts slow when cold, and not that fast when hot. I wonder if this could be a IPR plug? I wish I could find a picture of what it should look like. Anyone got one? If the IPR was to be unplugged, would the truck run at all?

If it starts, it's Not the IPR (Injection Pressure Regulator). If unplugged, the engine can't run...

EBPV is the Exhaust Back Pressure Valve. If it's either of the two, it would have to be that.

Dang, after reading posts of the IPR causing low mileage, low power and hard starts I was getting excited. I have never been all that happy with the performance of this truck. I chaulked it up to just being that way, maybe it is? I will have light on my side in the morning and I am going to try to figure this out. Thanks for the ideas! Anyone who has another idea please chime in. A pic of the ebpv would be helpful.
