Okay so my s5 rx7 has faulty wiring or something the RPMS stay for a while then my tach just drops to zero and of course the car still works. So does anyone know what exact color am I suppose to use from the coil thanks.

 

be more specific.
Like why did you title the thread "auto to manual",then start talking about Rpm and coils?
.........it only gets harder..so if you are detailed when posting you get straight up answers!

 

Lol very true I named it that because this car use to be auto and converted to manual I should have added that.
