Hi all, i have just recently installed a Crane Hi6 multi spark CD ignition system into my Sud race car.
My question is the two wires coming from the distributor (Marelli) Blue and black, what is the polarity on these wires? As they come straight off of the HEI module below the coil and now will connect to the CD box.
Some help would be great =)

Crane Hi6

The marelliPlex system comes in two versions. One has multiple wires from the Distributor, the other with only black and blue.

By looking at the connections that are made in the MarelliPlex you can discern which is positive and which is negative.
On the HI6 you will use the signal wires (pair twisted together) to the dist wires. If you pair them correctly the Crane box (turned on) will light up the small red signal lamp, and it will flash when you spin the distributor (by hand) If it doesn`t flash reverse the wire connection.
