Wiring a yellow/buff colour. Restorations are always re-wired.Pipe work,depends where it is. Oxygen lines were indeed usually blue but others seem to vary somewhat and appear to be copper/brass/aluminium colour. It can be almost impossible to tell from B+W photos and,as Graham said,artistic licence is often used. A lot seems to have been oversprayed in the interior colour (02 or 66) particularly on aircraft that have been upgraded or undergone major repairs.
I'll be home later today and think I might have a couple of good piccies I will check for you.

Edit. I just checked the link to the cockpit painting guide and would agree in principal with the "pipework" colours but not this.
"Reichsluftministrium (RLM) regulations state that prior to November 1941, cockpits/crew areas were to be RLM Green-Gray 02, with the exception of instrument panels, which were Gray with black instrument faces. After November 1941, all cockpit/crew areas visible through the glazing (windows) were to be RLM Black-Gray 66."
The RLM order was indeed issued at that time but it was really catching up with established practice and not dictating it. For example many Junkers and Heinkel bombers produced in 1940 prior to the BoB definitely had RLM66 ineriors,either entirely or in visible areas. The colour may well have been applied by Heinkel before the war! Some Bf109s (we are talking Es here) also had some or all the cockpit interior painted in RLM66 at the time of the BoB. I would use the quote above as a guide,particularly if you don't have a good reference for your model. I don't think it is safe or sensible to make such unequivocal statements about any aspect of Luftwaffe colours. There are many RLM directives which were either wishful thinking,particularly late war,and were never implemented by the manufacturers and there are many which were covering what the manufacturers were already doing. Messerschmitt in particular was often months ahead of formal RLM directives.
