OK what type of speedo cable is on a 4th gen H22? Because my old one off of my 3g si doesnt work with my swap....I was told the 4th gens are electric and i do know for sure the 3rd gens are cable driven....so the electric cable will work with in my chassis right????

 

The 90 and 91 are eletronic sending units that controll the speedometer and they are crummy. And I know all 4g are also eletric. As far as makeing it work if your cable in your body fits the h22 tranny i say go for it. If not get a dash from a 91 with an eletronic speedo and tie it into the eletronic sending unit on the 4g tranny.
