Gauge cluster repair and SI board replacement 1985 BMW E23 745i (E24 & E28 similar)

Going through the VDO instrument cluster on my E23 BMW 745i and explaining why the original cluster is junk, replacing the SI board and fuel gauges on the temporary replacement cluster. This is just so I can get the tach and temp gauges working and see what RPMs the engine is idling at and the temp while I continue to work on it. This cluster is similar to E28 5 series and E24 6 series. #7series #e23 #bmw #bmw745i #projectcar #e28 #e24
