in the MSD wiring book I find....

regarding pickup wiring, page 13 states: the black/violet wire is negative while the black/orange wire is positive.
regarding wiring at the MSD 7 box, page 73: M+ is violet and M- is negative.
who ever had these units cut the connector off. so I have no idea which color went to which. as is I have violet to violet and orange to green the engine runs. but I dont know if it correct. why would MSD have one violet - and one violet +. that makes no sense
somebody must have a correct unmolested wiring. will you help me please.
thanks Rod in AZ
