MSD Polarity

msd wiring

The question always comes up  "Which way do i hook up my MSD dist. to my MSD box?" If the ends have never been changed then you cant mess up because the connectors are indexed. But in the case where the ends have been changed, this is the correct way and sure fire way of knowing how it hooks up. Always the orange striped wire coming from the dist. is the + polarity. The violet wire on the box is the positive polarity, make sure these two colors are together.

Another tip, to keep the connectors together in a harsh enviroment such as a dirt track or even a drag car, we suggest zip tieing in between the wires and around like shown in the picture above.
