Hey guys i just bought a 66 mustang with with wrong guage cluster readings like for example the gas reads full really when there is none like when i was driving it home and it ran out of gas heat temp says hot and etc so please help me Thanks

 

Are you saying that the gauges are pegged out all the time? If so you may need to replace the instrument cluster voltage regulator. ICVR or IVR. I would recommend buying or building your own electronic one. The replacement ones are not the greatest at all. You could also have a problem with the gauges being grounded out.

Here is a link about making your own. http://chris66dad.tripod.com/id29.html

I think NPD sells one.
