2MuchNos93LT1

Whats up everyone, I just bought a digital 6 plus Ignition box for my 1993 LT1 z28 I installed it and it works but it has a pink and blue wire one for retard and one for rev limit I connected them to a 12 volt source and it sounds like its missfireing at low rpm almost sounds like red line I play with the dial but nothing how did you guys connect this? can you even retard or set rev limit with a 93 car?.

thanks in advance
