this may seem like a dumb question, but iwas wondering if someone out there can tell me how to install my autometer tach(it has got the 4 wires-ground etc..) I have also seen that brothers performance sells a distributorless tach driver(says it allows simple installation of autometer tach) for 4.6 distributorless cars. One thing is for sure, I am going to drill any holes an baby! Anyone out there could tell me how to install this tach, or what I should do, please any help. Also has anyone out there used this autometer tach driver, is it worth it? How does that connect? thanks. Robert.
