Just recieved, plugged in and always active (junk)
2 step is always active even with leads unplugged (doesnt matter if power or ground is hooked up or neither). I've had one of these on the car prior with no issues. Spoke to someone with the same issue on a brand new one and they said they had to warranty it. Packaged 3/30/26 and purchased 4/16/26 but doesn't work. Shipped directly from Holley/MSD but when i called them they said i have to warranty through Advance Auto. An absolute headache when spending $330+ on a box with some wires. Will re-write review once warranty is completed.
Bottom Line No, I would not recommend to a friend
