Hello, my name is ***** ***** I will be glad to send you that schematic.  I will need you to send me the VIN off the vehicle so I can get you the correct information, please.

I do not have the VIN right off hand, is there any other way to get the schematic
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

I can send you what I can find based on the year, make, model and engine size.  Is the engine the V8 diesel?

Ask Your Own Chevy Question
Customer reply replied 1 month ago
it is a duramax 6.6
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

And is the van a 2500 or 3500 series?

Ask Your Own Chevy Question
Customer reply replied 1 month ago
2500is it possible to send the bcm as well?
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

And do you want the wiring diagram for the ECM, or do you want the connector end view, or both?

Ask Your Own Chevy Question
Customer reply replied 1 month ago
Both please
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Standby, please.  This will take a little while.

Ask Your Own Chevy Question
Customer reply replied 1 month ago
OK no problem
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

I will need the RPO code list to determine which connector end view to send you.  Inside the glove box there should be a placard or sticker that looks very similar to the photo I am attaching.  Please take a clear picture of that and send it to me.

The vehicle is not with me at the moment. It is at my shop.
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Without the proper codes, I can't send you the correct information.

ok the vin number is : 1GD675CI3B1172881
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

And the RPO code list?  I need that as well.

That VIN does not show as valid in the US.

Ask Your Own Chevy Question
Customer reply replied 1 month ago
Where would i find the rpo code list, and it is not showing in the US because it has bben imported to Mexico
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

The RPO code list is in the glovebox.

Ask Your Own Chevy Question
Customer reply replied 1 month ago
there is no glovebos this is an ambulance
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Then my only other option is to send you all the diagrams I have based on the year, make, model engine size, and you will have to determine which one is the fit for what you are trying to do.  Is that acceptable?

Customer reply replied 1 month ago
Sorry thisis the correct vin numberthat is great

It is a GMC Savana sorry about that
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Here are the connector end views for the BCM  These sheets also show the wire colors and the circuits they go to, so that should help you quite a bit.  GMC and Chevy use the same connectors and wiring.

Ask Your Own Chevy Question
Chevy Mechanic: J Hall, ASE Certified Technician replied 1 month ago

Here are the ECM connector end views.  Their configuration is determined by the engine that is being used in the vehicle.  Again, these also show the wire colors, sized and circuits they go to.  I hope this helps.  If you need any other information, please let me know and I will do what I can for you.  I wish you well, and thank you for using JustAnswer.
