2011 mustang gt.
I have a project that I'm working on and I need an RPM switch that I can signal, preferably, off of a coil. It will operate a solenoid(.45 amps/12v). I purchased a Summit RPM switch, it was defective, they sent me a replacement and it was defective as well(LED didn't work). So I am willing to pay any price but I just want it to work. I would like to run it off of a coil like my shift-light. Any help would be appreciated.
