Aftermarket Tachometer

Need some help, installed an aftermarket Tachometer from sunpro. hooked it all up but now the speedometer does not work and the fuel gage does not work. Anyone know whats wrong.

Check your fuses?

Did you punch it a couple times? That usually makes things start ticking...

Splice the wrong wires? ^ Check fuses? My guess, spliced wrong wires. Autometer had the wrong wiring diagram for my car, had similar problems.

slap it a couple of times :D
