RPM's Display Fail

Alright so my RPM's were not reading with the Chinese gauges (I assumed because it was Chinese). I have purchased the speedo from arshishb and the revs still aren't working. Is there an RPM fuse I could have blown?

Erm, do you mean you bought a tach? Or perhaps a set of instruments completely? Because speedometers don't show engine revolutions. :P

If your tach isn't working, either your ECU is toast or there's a break in one of the two wires that drives it. The yellow wire with green stripe goes to the ECU directly. The green wire with blue stripe is a shared ground for the speedometer and vehicle speed sensor in addition to the tach. I'd start tracing them back.
