Identifying cut wires under dash - M1165A1 REV

[GMVguy]

Looking at the under-dash wiring and trying to plan for the repair of the cut wires in the below pic. Can you identify which ones are cut?

Do you see the turn signal controller in other pics? That could be one cut bundle.

 

[GMVguy]

Yep - turn signal controller is missing! Hope that's all that's cut.

Sorry nope there are plenty more cut wires. Won't be too hard to figure out, these trucks are not too complicated. You will have wiring not included in any diagrams, that being the compressor and the IR light circuit specific to GMVs.

I saw that movie. Starring Tommy Cruze... Don't cut the black wire.

This won't be fun. With the drawing, test light or meter, lots of patience and a hand full of butt slices to save the day.

BOOM ! CAMO

Looks like four or five bundles... Best of luck, and hopefully no electrical components fried during the cutting when wires shorted out.

Thanks. This is not the GMV truck I referenced in other posts - this is the 1165 REV. I appreciate the encouragement - will trace em down!

PS - assuming the part number for the turn signal switch (6220-01-408-7785) is the same for all Gens, M998, 11xx series trucks, all through the REVs?

I may have a harness with the directional control plug, Ill look tonight.

Is this pic reversed? Either that or this is one of those rare British right hand drive variants.

Missed one, he will have to remove the plastic loom to see what is going on there.
As far as I have ever seen the factory did not use plastic loom so it is likely part of the GMV upgrade.

Definitely reversed. Good catch.

Yeah... some are for the turn signal, some are ends of the same wires, and who knows what the others are for. Can't wait to get this jigsaw puzzle home and figure it out. Will post more pics when I do.

Here is the directional harness I have, 15" OAL, number tags still present.

Look for wire numbers near the ends. All military vehicles and trailers use the same wire number for the same function. Somewhere in the past, the full table of wire numbers was posted on this site. Hopefully a copy of that table is in the TM Library section.

 

[Mogman]

Here is the common wire numbers.
Unfortunately he will not have the numbers where it will help the most, as Commo said allot of tracing wires.
GMVguy do you have a good schematic for that rig?
If not give me the serial number.

 

[Mogman]

Here are the schematics you asked for in the PM you sent me.

Awesome - thanks Mogman!
