I just did an H22 swap in my lude. The speedometer worked fine before we took it out, I'm using the same tranny. Some times the speedometer just starts going to 140 and jumping around, it has done this sitting still and while in gear. Most of the time it just sits at 0.... meaning my m****r f*****g vtec will not engauge because of it. We changed the speed sensor, same thing. We used the H23 wiring harness and ran the vtec wires, is there any difference in that area on the speedo on the H22 vs H23? Any help is appreciated.

 

Anyone?
