need help

[podagee]

i put an 89 hf gauge cluster in my 91 hatch and the speedometer works but not the rpm's and the temperature.do i need to rewire the plugs?oh and will the d15b7(92-95)intake manifold fit on a d15b2 head?i havent taken it apart yet but will the water jets line up?

yes you need to rewire them. if you had bought a 90 or 91 cluster then you wouldn't of had to. in this link you'll find pinouts for both year sets, 88-89 and 90-91.

99-00 civic si cluster swap into 88-91 crx - Tuner-Junction

the b7 manifold will work on the b2. not sure what you mean about water jets though..
