for you guys with aftermarket dashes and what not what speedometer are you using and how do you make it work with a honda

 

I also am wondering how you would hook up a Auto Meter Speedometer using a Honda Ecu?

 

Most speedos work off the VSS(vehicle speed sensor) wire. Speed is measured in pulses. Most honda and acura apps are 4000 pulses per mile. You have to use the calibration button and a 2 mile stretch. I use the autometer electronic in my integra.
