I recently replaced the heater control valve/heater water **** in my 83 280zx. Had to remove dash, heater box etc and vacuum lines. Lost the diagram I made of how to replace all the vacuum lines that i had to remove associated with the heater box. Anybody have a diagram of how to route these lines.

Thanks,

Pat

I have the same problem with my 280zx with air can you help me

His is/was an 83 and according to your profile yours is an 82. Here's a link to a 1982 280ZX service manual. Maybe it will have what you're looking for:
