Where Is All The Tech Help

I Wired Everything Up As Steve68 Gave Me .it All Hooked Up Perfect And When I Fired Up The Car And Nothing Moved. The Dash Was Grounded And There Was 12v To The Fuel Gauge But Nothinng Worked. Could We Have Fried Something? I Want To Keep The Rally Dash But Want To Drive My Car More So Custom Comes To Mind.
Thanks Guys, Steve

Sounds like the voltage limiter is blown or something isn't hooked up right. You should have +5v at the fuel and temp gauge... that's if the rally dash and stock dash are the same electrically speaking.
