Help anyone with a Volvo 140A wiring diagram or manual

[tr7v8]

In the middle of rewiring dash and have hunted high & low for Volvo manual in house. Can anyone A. let me know what the Brown wire does in the instrument panel multi block and B. Possible scan and mail me the Wiring diagram for this lump.

No doubt when I've finished the manual will reappear!

I've a wiring diagram for the engine....2 different ones to be exact! If you've got the original volvo instruments it shows the brown wire going to the temp gauge from the sender.
If I had a scanner i would, but I haven't....its in black and white anyhow!!

Barry, one of the problems is that Draco took the original Volvo loom and modified it and used their own USA made instruments. EG I have Ammeters on the dash rather than volts! This Brown wire is quite a thick one and I've traced & marked all of the others and I've got temp & oil pressure lines.
I'll have to go down to the boat and trace it through by the sound of it, but thanks for the try!

Ah well you didn't say that did you? So its a bit of a shot in the dark then init.
If its a thicky'ish type wire then your looking at carrying a fair amout of juice/heavy load. Dunno what it could be.
