The brake warning switch is on the master cylinder.
I would think the only way to calibrate the oil sender would be to bend the arm on the sending unit in the oil tank.
I would also ad that the later replacement sending units come with a note to use the newer dipstick. This is due to Porsche using a lower level of oil in the tank. The newer dipstick has the full mark stamped lower. Most likely done for the reason that most early Porsche owners found that oil was being pulled into the intake when the oil on early cars was filled to the maximum mark on the dipstick.
