I have a quick question on the wiring for the MSD 5520 unit.
I am currently running a voltage gauge that is connected to the "+" side of the coil and it reads the average coil voltage and it works fine. The instructions for the MSD unit say that the ONLY wire to be connected to the "+" side of the coil is the orange wire. Will I have any issues if I wire in my voltage gauge to the orange wire ("+") ?

Thanks
