Honda Repair: 88 honda prelude si 2.0, honda prelude, fire wall

Question
have a 88 honda prelude the speedometer works but the odometer and trip don't. (manual speedometer) and I'm not sure which cable coming out of the fire wall to follow for the odometer.

Answer
Zaq, not 100% familiar with these cars. But, you can remove the Cluster and look directly behind to find out what feeds the Odometer. I thought that they were electronically controlled but, that might not have happened until 1990 - 1991. In any case if you remove the cluster this will give you the info. you are seeking.
