I just finished hooking up the 7730 piggy-backed on my Mallory Hifire 6 box and Unilite Distributor.



Before ordering I talked to 2 separate techs at MSD to make sure it would work. Both had the same story. It will work fine.....On the 4 pin connector, Orange to B+, Red to Ing from Mallor box, White to Green Trigger from Mallory box, Black to ground. From the 7730 to the Distributor, it was white to ground, red to red, and the brown wire on the Unilite to ground.



Car fires up fine cold, and I ran it through some timing checks. As the motor starts to get warmed up, I noticed a very intermittent misfire. Worse at lower rpms.



Here is a video of what it is doing..........any thoughts or input would be greatly appreciated.
