Hi, having problems with getting New MSD and Hot-spark ignition to work on my 911 1976, 2.7L that has contacts in distributor. Have installed after this drawing from MSD : https://www.hot-spark.com/Hot-Spark-MSD-6-series.jpg, but i only get spark on coil when i jump violet and green togeather, but not from distributor. I have a red wire from Distributor to red on MSD. A black from distributor to white on MSD ( but white has 12v when ignition is on) Green and violet from MSD i haven´t used. What am i doing wrong
Help my friends , cheers from mike

That diagram appears to show a special distributor from MSD; you should only have one wire from the Porsche distributor and that would go to white on the MSD and the red on the MSD should only go to a power source that is only on when the ignition is on and not to the distributor.

When you say contacts in your distributor, do you have a petronix installed or just the standard points?

MSD has tech support that could be helpful.

Well there are two wire from distributor, that is because there is installed a HOT_SPARK electronic ignition set.A black and red wire
