I studied your pics. There are wires missing from the buss bars. Warthog made a great observation. We have a partial 12 volt conversion here.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
I was more confused by the fact that the Emissions sticker mentioned spark gap, I would agree it is not the stock core support. Thank you for the heads up on the breather cap.You can ignore the emissions sticker on the core support. That is not pertaining tro that M1009. They do not have catalytic converters. I would say the entire core support has been changed. Also I would get a breather oil cap on the engine. I know that one fits but it could be detrimental to the life of the rear main seal. I know all of them had breather oil caps. Other then that it looks complete. Good Luck. What are you plans for the vehicle? Keep it white or repaint in original colors? Keep us posted. I have one that someone bought from me and used hard for 20 years it is still running and used / played hard. That is my Terminus M1009.
I wouldnt have even considered a push button for glow plugs! Awesome observation, I will check that out tomorrow and report back.Looks to me if that is a push button switch below the BO Switches
It's probably for manual glow plug control.
Need to verify.
Is that a serpentine belt crank pulley?
I think I see V pulley but not sure what else I'm seeing.

Wait, the glow plugs are never supposed to receive 24 volts? Military or civilian Glow plugs are 12 volts? Or does the GP controller want 12 volts and the GPs themselves want 24?Wow what a mess. Starting to look like a 12 volt conversion not fully completed. Would explain the disconnected pass side alternator. You will need to peek at the starter and try and find a part number to look up to see if it's 12 or 24 volts.
The glow plug relay is the small can on the firewall to the right (as seated in truck looking forward) of the brake booster. Should be 6 wires on it. Large red wire from power. 2 large orange wires to the glow plugs. Might be a small orange wire connected to one of the bigger studs. Goes to GP controller for voltage sense. The smaller studs will be pink/black which is 12 volts. The other is lt blue which grounds through the controller to turn on the glowplugs.
If the big red wire goes to the buss bars on the firewall by the heater then that would provide 24 volts to the glow plugs. Which is too much as they are 12 volt. Now that is only IF the truck is still wired as 24 volt. If they had 12 volts going to the buss your GP circuit would be okay.
In the normal stock setup the front battery negative goes to chassis ground and the negative buss bar. The positive goes to the negative on the rear battery. There is a wire coming off this which goes to the 12 volt junction block. That is also near the brake booster. That provides all the 12 volt power for the truck. All comes from the front battery and I believe the drivers side alternator charges it. The rear battery positive goes to the positive buss bar. From there it would normally go to the starter, glow plug resistor pack and feeds a set of bus bars in the back of the truck to feed the military radios.
Hope this helps.
BTW where in Tacoma are you? General area. Don't need your address here.

Warthog made a good observation regarding the 12 volt power wire. In looking at your pics the 2 buss bars are missing some wires and have definitely been modified.
Very specific, thank you so much. I will be able to investigate this tomorrow.I am also wondering about the wiring.
The wire on the MAIN terminal bar should not be there unless they attempted a 12v conversion. It looks like it goes to the 12v terminal block

Please confirm where it goes.
Again verify your wiring before hooking up the batteries.
The military origins are interesting, even still has the Military ID plate in the door jam. To me the bumpers are a shame, but not as much as the AXLES. Im so sad that it is back to six lug axles.There are military fixtures that don't come from the factory in civilian versions in that truck from the pictures. Get the VIN and post it up that's the only way to know the origin, but it looks like someone made a M1009 into a civilian truck (paint, new dashpad, grille, new bumpers... it's shame on the bumpers). When people paint these trucks, they often don't do the engine compartment or under the dash - you can see in the engine compartment the original 383 green, and I'd guess that under the dashboard the metal is still green also. Can't see if there is a 24V voltmeter in the dashboard upper right corner above the heater controls.
Be careful putting a 24V set of batteries in there before tracing out the circuits. In general the terminal block on the passenger side firewall is supposed to be 24V and ground (big one on top is +24V, small one on bottom is GND). The two-terminal block on the driver's side firewall is 12V, and that feeds the standard fuse block. Only the GP relay, starter, NATO slave port on the grille (missing on your truck), the voltmeter, and the radio power terminals behind the passenger front seat inside the truck are supposed to have 24V. Everything else is 12V just like in a civilian truck.
You called it, that button does indeed activate the glow plugs. How long should they be run for before starting the truck?Looks to me if that is a push button switch below the BO Switches
It's probably for manual glow plug control.

This has helped more than you know. You called it, 12 volt conversion.Wow what a mess. Starting to look like a 12 volt conversion not fully completed.

I was confused, thank you! I thought the M1009 was a 3/4 ton, but obviously my memory had failed me. Thank you!Im so sad that it is back to six lug axles.
Back to 6 lug axles? It came from the factory with 6 lug axles if it is a K5 M1009 Blazer. They had Corporate 10 bolt rears front and back.
I have a local guy that swears all the M1009's in his unit had 8 lug axles. I beg to differ. Good Luck with the project. What is a shame about the bumpers?

In the stock system, the GPs are 12v. However, GM knew you would be buying a used, converted M1009 some day, so they decided to make it extra confusing just for you. So, the 12v GPs are fed from the 24v buss, through a resistor that drops the 24v to 12v. Fun, huh?Wait, the glow plugs are never supposed to receive 24 volts? Military or civilian Glow plugs are 12 volts? Or does the GP controller want 12 volts and the GPs themselves want 24?
I thought one of the buses on the passenger side firewall was 12 volt and the other was 24, knowing that one is ground makes me that much more confident this is a 12 volt truck.
(24 hours ago this was for sure, in my mind, 24 volts. This piece of the puzzle tells me it most likely is 12)
