1989 525i brake light issues, and

Hi, I have a 1989 bmw 525i ... I have problems with the entire
insterment cluster going dead when I push the break pedal... it only
seems to happen when the car is cold. It also seems to be affectied by
the high brake light in the center of the rear trunk by the rear
window. If I pull the bulb it seems to help, and sometimes it does
not... if I pull the bulb, I do get the message " 1 brake light out.
but when the car is cold, or not been started for awhile, it still
flakes out.When it flakes out, the oil gauge and fuel gauge are also
effected, It sometimes is intermitent, and some times all is ok...
provided I do not press brake pedal when car has been sitting for
awhile. All the symptoms happen only when brake pedal is puished I
have some experience at electrical and have the wiring diagram. Also,
when warm, if I turn the head lights on.. when pressing the brake
pedal, the insterment cluster dims,, Is it possible that the lamp
control module needs to warm before everything is ok, would it flake
out when the car is cold, or not been run, started and warmed up ?
