Detroit Wiring Diagrams

PushBroom do u have the diagram of a 1998 Volvo 770 firewall by the driver left leg, I need to see where the air lines and wire go to

 

Thank you! Honestly couldn’t ask for better help. I’m new to the game. This forum is blessing for the community!

 

Thank you for the diagrams. I have a 2009 so I believe it is DDEC VI. By any chance do you have these or know where I can get them? Thanks.

 

Ddec 5 engines, 2004 and over, NEED the cab ecu as "central gateway"

 

This is what i have, hope it helps

 

Thank you for this. I wish I had seen this 2 years ago when you posted it.

 

Wondering if anyone would have the electrical diagram of 2002 FTL Century HVAC
