If you remove the plug, you will be able to use a magnifying glass with a flashlight in order to find each PIN number on the plug. Then you can connect it to the appropriate wires by using the transmission manual and the electrical manual which will show you where each wire number attaches to...

Buy the plug look for a little metal crimped on tags that are about 3 mm thick. Each one has a number and that number defines the wire.

There is a transmission guide that you can look up however first I will point out that your transmission light is not coming on implying that someone either cut or disconnected the 12 V power line leading to the transmission control module under the driver side rear seat. Before you start going...

Get thin steel or Aluminum rod. Bend to shape. Cover in Canvass or rip stop or whatever. Get clear cut plastic and zippers and you have doors…. Or do what I did and use 1/4” Aluminum sheet and cut a set.

I want to make clear that the high jack lift is absolutely unsafe for lifting. It works and it can also kill and maim. My runflats will do the heavy lifting until I get to a safe area where I can change a tire with a proper jack. That being said… I always carry an high lift, and you might ask...

My vehicles live there. Hummer H1 has 300,000 miles and has lived there.

I love these tow bars. Heavy. Yes. Cumbersome. Yes. BUT SECURE when used properly.

Thanks excellent information!

Where do we order new driers? Are there substitutes for military?

Great question for the electronics part of this forum

The OP first joined in April and was last seen in May 2025. Unlikely he will respond. The first thing I would check are the bolts holding the rotors to the calipers.

Easier to pull top of IP and inspect the relay. IMHO. If you go this route: Three screws. Shallow screw heads. Heat quickly before attempting to unscrew. If they strip, dremmel a deep straight groove across the middle and use a flathead screwdriver. Once out, hit with 24V and check solenoid...

I don’t understand your thought process. How would a bad alternator feed current to the cutoff solenoid on the IP?

You misunderstood. RWH is a prominent member on this forum as well as several HMMWV Facebook sites. Read his posts and learn, and when he makes suggestions accept them and learn from them

M1097 means your vehicle was rebuilt. Does not mean M1097 is a specific model. M1097 is a catch all poorly descriptive “bastardized” term that includes several iterations IIRC. From the v-belts and three speed shifter you can start by looking up M998. Your dual voltage alternator might be...

We are all happy to help. FYI, Technical manuals (TM’s) are free and downloadable at the top stickies and also in the TM forum of the website. That might help with some of your questions.

Start your Humvee, open the hood, and undo the plug on the engine side of the PCB protective control box/EESS smart box. If the engine stops, then it is possible that your problem is the box. If the engine continues running, then you have some other problem.
