hello men .I have a problem.so I have a Isspo 3"3/8 tachometer Whiteface blue letters chrome bezel .
#1. I bought the harness that Geno's garage had .
#2. and used it with and without a filter.
#3. Hook it up to my original wiring harness underneath the dash to the colors that they said and to the colors that I read on a good post
I can't even get this thing to move.
the rpm tach is sitting on 3500 rpm all the time is there something wrong with my tachometer?
and what is fluid dampening?
