That's the WTEC III transmission control module. Start calling and messaging the surplus truck and parts guys on here and on the wider internet. Someone has a parts truck with a harness. The biggest problem isn't going to be finding a harness it's going to be finding the exact same harness used...

Yikes. That's horrible. Ideally you should replace the entire harness. If all the wiring in the dash looks like that - there's not really any good options besides finding a donor truck with a better condition harness. That level of insulation deterioration speaks to a very harsh environment or...

I mean...... acronyms are just a fact of life in any technical field. Also "jargon" - you just have to immerse yourself in the FMTV ecosystem (well - and electronics, and mechanics, and welding, and all aspects of DIY ownership of "technology") If you are on this forum regularly it's probably...

@Suprman has the kits. I think this is his listing: https://www.ebay.com/itm/194371219358 FYI - these latches are shared between the FMTV's and the F22 Raptor fighter jet. Such a weird cross-over. :cool:

You don't want to do that.... Having a belt connecting the two alternators that are each driven from the crankshaft pulley on their own belt will be a nightmare of belt length and tensioning problems. The CUCV has a similar problem with it's power steering/#2 alternator belt situation. It could...

Yep - have to consider how much belt wrap you will get on the pulley. So an idler to increase wrap and power transfer is likely required with two alts.

I'm the only one that I'm aware of that has done that repair. I'll PM you.

CUCV uses two Delco 28si isolated ground 12v alternators. It works. There's not much space to work with so the mount will have to be carefully designed to avoid being too close to the cab, etc. I wouldn't start with modding the factory mount since that's not likely going to make efficient use...

Electrical Load Analysis would be my assumption given the context.

And this is why I run a 300A Niehoff 12/24 for my (4x) 6TAGM system. In interest of redundancy when off-grid I prefer to keep the four battery system. If I lose a battery I can reconfigure to two. Can't get 24v from a single so the 2x system has no available redundancy.

C7 gauges are CANBUS to the MMDC and more than once I have had a gauge not completely/correctly calibrate after engine start leading to erroneous readings. More than twice one of my voltage gauges has failed to correctly calibrate and read high till I power cycled the truck and it went back to...

Sometimes you don't want the operators or even the field techs to pop in another fuse or bypass the fuse easily. The AIH is very high current draw and a malfunction down stream from the PPD/LBCD could easily cause a fire. When that link burns through the techs will have to go into the TM and...

Cant read your list - image is too small. If you haven't considered it. Being the year it is and being the 3126b - based on my experience I would recommend the following as well: Engine oil pump: HEUI high pressure filter kit. (https://ifskit.com/) Bypass oil filtration. Thermostats. All...

This is why a laptop setup with Allison DOC, CAT ET, etc is an invaluable tool for the the DIY owner of our trucks...... unless you have just piles of money laying around that you can afford towing / recovery to a professional shop when any of the computers goes on coffee break. You can't...

No. They are specific to the M1079. The M1087 (MTV Van) is totally different.

You can likely just slap a label on it and have Fastenal move it. They probably wouldn't even care if it wasn't on a pallet. It's light enough to carry it around easily by one person.

Call Fastenal. They ship between their stores cheap. No guaranteed delivery date is the catch.

That's a fusible link. It is designed that way on purpose to burn through if the rated amperage draw of the heater exceeds it's rating. A "fusible link" is simply a section of wire that is intentionally several wire gauges smaller to contain the failure to a specific location. It's just like the...

Yeah the Bluefire dongle seems to be a good option for basic monitoring. Note that for some strange reason they don't make it compatible with the 24v J1939 powered port on our trucks so you have to either modify your plug or add a second interface plug that's 12v so it doesn't damage their...

Well..... you can't. Not *legally* without paying for it anyway. And it's prohibitively expensive. The military has a somewhat reduced functionality version of CAT ET that doesn't require registration, etc but getting a copy typically involves offline methods due to size and potential for...
