Stumped, need help with my 84 blazer

[Durrr]

Hello, I have myself a basket case thats got me scratching my head.

The p.o. Sold me an 84 military blazer body on a similar year civilian chassis.

He basically took the best stuff from both vehicles & sold me the leftovers.

The motor is a 6.2 diesel, im having wiring issues right now and dont know what I'm missing.

I was given a harness that goes with the chassis but theres wiring coming through the firewall that doesn't connect to anything.

If anyone has pics of a civilian diesel engine bay & a military engine bay that would probably help alot.

I may be over thinking this but here is a list of my problem areas.

-cable from the trans, don't know where or how it hooks up
-heater hose, can only find a place for one (top front of motor), where does the other one go
-glow plug wiring, this might be redundant. The wires run through the firewall to a control box. Is this military only? The truck is being wired for civilian only
-how do I know if the body is on a 24v setup? Everything needs to be 12v
-want to run a single battery on the passenger side, is that possible with the diesel? 700cca
- any pics of how all the positive & negative cables big & small connect to the battery. Am I missing a distribution block or something?
-ignition & starting wiring is still a bit unclear. There are two negative leads down by the starter how/where do they connect? Still not sure which wire is ignition.


Those are the big concerns, ive researched military pdf's, bought a chiltons manual & tried searching the net but I'm coming up short.

Thx in advance for any help.

Update, I'm having a real struggle with the glow plug wiring. Here's a few pics. The first pic shows what i believe to be the wiring to the glow plug control box. Where and how do these leads hook up?

Here's a pic of where I thought the glow plug wiring was supposed to be. Any buddy know what's missing?

Here's a pic of some random wiring, I really have no clue what that green connector goes to

Here's a green connector that I don't know what it's for

Here's the glow plug control box I believe


I did buy a glow plug selenoid that looks real similar to a ford starter selenoid. I have no clue how to wire it in because so far I can't figure out which wire(s) supply power to the glow plugs.

Post pics if you can so i can compare, thx!

More wiring questions/concerns. I believe the larger plug is for diagnostic testing but what about the smaller one right next to it?

Here is the old alarm wiring. I believe the p.o. Hacked into the ignition wiring and bypassed the neutral safety switch. I have no idea how to get the nss working properly. Any suggestions would be a big help



Honestly if no one here can help me out please send me a link to a forum that might, or whoever knows how these trucks are wired. Thank you

I've got one of these trucks but do not know how to put one back together like that. I just haven't had much trouble out of it. One starter and a pair of batteries is it. I know I can figure it out as I need to but there hasn't been any need yet. You can get the service PDFs at steelsoldiers.com and there's a bunch of 6.2 diesel fans at thedieselplace.com. There's some 6.2 knowledge here but not concentrated like at those two spots.

Some of those wires look like a alarm setup and not factory.
I posted some things to check in your thread over at dieselplace
