I have been trying to find the answers I seek for weeks now... I'm just starting out in the grand world of muscle cars. I just bought a nice set of glow shift gauges (http://glowshift.com), one being a nice 7 color tachometer I'm going to install on dash. Everything has been installed and looking great except for one wire... The most important one, the tach lead... Well seeing my car is a v6 I have a core pack meaning I can't just tap into the Negative pole on the first core (due to the fact I have I think 2 cores to one pack) so thing get a little harder... Has anyone found a tach signal for the mustang 06 v6 yet? Or is there even one? I hope I don't have to pay an extra $80 to buy the dang "Tach Adapter" to run my $50 Tach...
