MSD 6al issues - bypass ballast resistor

So i bypassed the resistor and the car started and ran OK but it is very difficult to start - doesn't just fire right up.

I have a mopar performance distributor which has a grey and orange wire for the magnetic pickup. MSD instructions say there should be a black and orange wire and black goes to MSD green and orange goes to MSD violet. I assumed the grey was black and hooked grey to green and orange to violet. I am wondering if it should be the other way around since I read in other forms that reverse polarity will make it hard to start and not run well.

Does anyone have experience with the mopar performance distributor and which wire is negative and which is positive? Out of grey and orange?
