Just to take a stab in the dark due to logic. Your ignition should retard due to load, meaning that if the intake pressure goes from vac, to atmosphere, your on WOT. So this would tell me that you want the retard side connected to the one closest to the intake, and the advance would be the other one. But i'm not sure so don't take my advice too seriously.
