I am using the yellow wire to give my shifter relay ground and break contact on the shifter relay. It has worked fine since install until wed, on wed the shiftEr didn't activate. I verified settings in grid, and have checked my relay. When i put ground to yEllow wire it works. So I am guessing the grid may have shit the bed. Is there a mystery setting I need to be aware of or do I need to send it in on Monday ?
