hi, first post so bear with me. bought a converter from ebay and instructions say to wire it to the gearbox speed sensor. ive look all round but have no clue where it goes. please help i have a 1995 integra coupe. a picture would be very helpful lol! thanx

 

I have no idea exactly how that would work. The VSS normally sends pulses to the speedometer. I'm guessing that this device simply modifies the pulse signal.

Another option would be to get a new gauge face.

 

The gearbox speed sensor, also called the vehicle speed sensor (VSS), is located on top of the gearbox (transmission) towards the rear. The whole assembly to the right of the diagram is the speed sensor.
