ive got a Eg hatch with a k20a3 swapped in right now. do i use the stock ef speedo cable or what? speedo isnt registering

 

eg vss are drive by wire.. why would you wanna swap an ef drive by cable one in .. you can use the stock k20 vss(drive by wire just like the eg ones) with your eg cluthers just gonna be reading a little off. and plus if you add'd an cable vss it still wouldn't work the gear on the vss are not the same and plus the ecu need to read your vss or else your gonna have a c/e light and vtec wont happend.... ^ is that you jason?
