Coming on nicely Sir P. I hope you got a detailed wiring diagram or are the wires simply extended
MADMAN
Got a fairly comprehensive wiring diagram. Most wires are extended from the three coloured plugs that go into the back of the instrument cluster printed circuit board, then some come off the light switch, some off the three new senders (oil temp/pressure & water temp) and a few can be connected straight up (fog lights for instance, & A/C)
Trouble is that there are many awkward colour combinations that it is almost impossible to replicate (for instance the fog lights are again a good example; the four wires are yellow+blue, yellow+brown, yellow+light purple and yellow+dark purple....) each one will need to be extended with the coloured wire I can get hold of....so its all going to get a bit complicated.
Hey. Looking good. Is the dash supplied or modified from the Beemer’s original?
The dash is/was a DNA moulding. The front of the original BM dash is retained (the bit with the windscreen vents) so is the associated pipework ...then the new dash is joined to it on the moulding curve....you just loose the "eyeballs"
