What are these?

[sht2kll]

I found the plug with the resistor taped up to the wiring harness in the back of the engine, and the plug with the blue wire was just hanging there. Does anybody know what they are for?

I can't wait to hear a response on this one. Not so sure about the one behind the engine, but my 1008 has that same loose blue one near the master cylinder. I have been scratching my head about that wire since I got the truck. My assumption is that it's not utilized in our trucks.

That looks more like diode that is stuck in their. I don't know about you but that would bug the heck out of me having that flopping around in the breeze without any insulation on it. Time to break out the big shrink sleeve?

I'm sure if you pull up the schematic it will show what the connectors are for. Plus it's a good way to get to know your machine.

cant help with pic 1 but I am 99.9% certain the wire in pic 2 is a connection for the STE/ICE...
Now ask me what a STE/ ICE is.

**** Edited to fix MY mistake ****

The Diode is for the Water in Fuel circuit (diagram E-1 or F-1) and the blue wire is not used on the stock M1009 and M1008 and does nothing.

The blue wire is used on the M1010 for the box heater and with the arctic heater kits.

Can you find this on the wiring diagrams? I have checked them all and didn't find it. I may have overlooked it.

Any pictures of what it is connected too?

When I took a wiring harness apart on a M1009, it was in the Glowplug harness and was on one side of the connection but the other side was empty.

Wrong on all accounts except for DIESELGREEN.

The Diode is for the Water in Fuel circuit (diagram E-1 or F-1) and the blue wire is a left over from Glowplug System and does nothing.

lol thanks funny guy. You must have that rare selective vision problem. I said it was a diode. And how is it wrong to insulate it so it doesn't short?

Look at E-22. Photo from my M1010 included.

Ha..... you are absolutely correct..... I made a mistake and I did miss your post. Thats what I get for typing while trying to do my real job.


Please accept my appologies.

Thanks for the picture.

Upon futher digging, the blue wire is indeed used on the M1010 for the fuel pump on the rear heater. Diagram E-22

Looking at E-28 it is also used for the Heater fuel pump of the Winter Kit, but the wire is not labeled at all.

I learn something new every day.

thread hijack alert...

lavarock, what is the silver cannister in the picture at rear of photo right side?
And the finned thing at front of picture. Is that an inverter and if so what size and what are you using it for??

The silver canister is the fuel pump for the fuel fired heater in the rear of my M1010. The blue/red wire provides 24v to the fuel pump.

The finned device is my Sure Power 52210 battery equalizer. It provides 100amp of 12v power from the 24v system in the M1010. The M1010 has two 24v alts and the 52210 replaced the stock DUVAC setup. Search "no more duvac" for my thread detailing its purpose and installation.

Thanks for the help. I insulated it when I put it back. I will leave it alone. I find that this truck is a delicate flower, if you touch it, it will break!
