You guys that are running aftermarket speedometer gauges, what speed sensor are you running? I'd like to use a Koso gauge, and I see they come with a replacement speed sensor, however I'd like to reuse the stock speed sensor. If this isn't possible, I understand, I can see them having different resistances. However, if you didn't reuse the stock sender, how did you block off the stock sensor port? Clipping the wires and leaving the stock sensor as a plug is kinda trashy.
Send member Sebspeed a PM. He just got finished with a street fighter build, he would be a good go to guy on this topic.
