here's what i found in trying to do a V6 cluster in a I4:
- the tach is off..by a lot, and no, moving the needle won't work because it is off in varying degrees as the rpm's change.
- the speedo will not work. you can't put your speedo into the gauge cluster since the plugs are different. and i tried swapping boards, it can be done, but the speedo still doesn't work.
- the gas gauge will be off, trust me.
--the only way this will work is if you find a Contour "Sport" (I4) you can rob the gauge pod out of or if you find a I4 mystique with a speedo--
i tried just about everything to make it work and i just wound up throwing it away and putting my old one back in my car as i search for one that will plug and play.
