Just did a H22A swap in a cb7 93 coupe ex 5 speed, my speedometer is only working sometimes. I replaced the vehicle speed sensor since i had two one from f22 and one from h22. Its a h22 tranny when I first put it in the needle went up as if its going to work jumped around and then back down to 0. Can someone give me any ideas to what I should do to solve this problem. I have no vtec untill i get this problem solved.

 

bad wiring. the pin in the sensor is stuck? bad sensor?
