Hi again Jonny!! I've been driving without a tacho for a while and have decided to delve into this topic again. On further inspection the purple and black goes from the dizzy through the 14 pin connecter and on to the rpm transducer. From the tach end it goes through the 14 pin connector and into the rpm sensor (Bosch can). So the two don't even meet. Advice? Should I connect the rpm transducer to the Bosch can so it flows through both, or bypass the transducer and connect at the Bosch can? With the MSD do I need the transducer? Thanks Jonny, anyone also lease free to advise.
Cheers...
