My schematics show an external LED that you can mount anywhere. You can also disconnect the “wait light” from the dashboard system and connect to my box’ designed LED wires. Use Packard Connectors from my box to the stock “wait light” wires. Just make sure you get the polarity correct as LED’s...

Agreed about that being a Prestolite. I have several that I opened before creating this thread. Prestolite has robust solenoids that can be reused for a DIY project. Self tapping sheet steel screws will close it nicely. Drill the top hole larger than the bottom so the screws act like lag screws...

Sounds like you have a three speed transmission. If you forget to place tranny in neutral, she won’t start. You will curse and think something is wrong. Drive in H and NOT HL because HL is for sandy muddy slippery surfaces.

Happy you did this! Good on ya’! The LED I included in the diagrams is to show if the glow plugs are functioning. If all 8 are dead, my LED won’t light BUT the dashboard “Wait Light”/LED will. Happy to see the relays you used will support 200 amps each. Where did you source them and are the...

still havent been able to source these units

You need to look up the specs on the transmission gears, transfer case gears, rear end gears and hub gears If you have 2.56 diff gears and all hubs are 1.92, then you just need to google 4L80e transmission gears and then google the transfer case gears in your rig. Then factor in 37” diameter...

Welcome and thanks for your service. TM technical manuals are on this site for free. FYI

CamO makes a flasher device for this area, so he knows it quite well. If he says it is rust… it is probably rust.

Ready Brake is a great thing for flat towing. I can’t speak highly enough about this gasket. It activates the brakes of the rear vehicle to make control much better.

Great video CamO!

Silly question BUT can we be sure it’s not the switch?

So you’re still considering this fools errand? Just buy an Alpha H1 Hummer. It will be cheaper and guaranteed to work and it will retain value and give immediate satisfaction.

Happy cloud. Welcome. It looks like English is not your first language so I will try to use simple words that a translation program will understand. No one makes different gear ratios for the gears in the hubs. There are some gearing options where the gear teeth are angled (herring boned) for...

Someone on this forum (for all I know it was you 😉) posted images of the first test project/demo HMMWV. It had that Deutz air cooled engine. It was a much lighter concept vehicle.

That Deutz was underpowered. And in desert conflict I bet it would have failed.

Like a fine wine. More collectible and worth more.

PM (private message) me. I can tell you how to rebuild your box or I can sell you a rebuilt box that eliminates all the failure points with pushbutton activation for about half the price of others on the market.

These trucks are great until 60/65. Then they are like bricks in a hurricane. They are not geared or streamlined or designed for speed.

RWH is of course correct. Still, search the OLD posts. People have installed in many novel places.
