I didn't mention in my question that my 70 has the GM 'connect and cruise' package which has a speedo and tach wire available. I am using the speedo wire on a dakota digital ecd-100 to drive a mechanical speedo that I got from LMC which has just stopped working. I haven't had the chance to trouble shoot.

I am going to try to put in an S10 speedo with the ls1nova71 mods in a gauge cluster I just acquired. Would like to put in a tach at same time.

Most of the after market tachs don't seem to look right.
