Msd 6c

I looked at those, this unit is older and it has the 5 pin on one end where you disconnect the orange box and put the plug onto the MSD. Then there is a single spade plug on the other end. That's the one I'm not sure about.

I'm almost leaning to the tach output, but I need to be sure.

I just scored a bunch of Mopar stuff today, woohoo.
