Default MSD 6010 tachometer problem

I installed an LS1 in my 1948 international pickup and the yellow wire from the MSD 6010 does not operate my tach. I am getting a 3.3 to 4.4 volt reading on the wire. My tach is an older ( but good) Equus tachometer. Is the problem the 12 volt Square wave signal will not work with an older tach? Or is there a fix for this? Is the MSD 8920 the fix? Do they make an after market tach that works with 12 volt square wave signal? So many questions so little time
