I have an 89 civic hatchback dx automatic trans,
and i bought this cluster that has km/h instead of mph.
and when i installed it tach and speedometer dont work.
Right turn signal blinks on the high beam.
is there any wiring changes have to be done on these cluster?

 

you probably got a 90-91 cluster.. There is probably a wiring conversion diagram somewhere, though if the speedometer doesnt work, the cluster itself might be bad. That should at least work..

 

nah its an 88-89. i know how 90-91 looks like cause i have one with me right now.
ive bought several 88-89 cluster with a tach but none of them really work properly.
but my dx cluster without tach works so well.
anyone have experience?

 

did you repin the wires for the 88-89 cluster? theres a slight difference between the wiring for the 88-89 and the 90-91 clusters

Please read the description.
I have an 89 civic and bought an 88-89 Crx si cluster not a 90-91.

 

There are two different mfg of cluster, make sure you replace one for one

- NS
- Denso

 

i had a denso cluster in my hatch with no tach and swapped a canadian nippon seiki km/h cluster with tach in no problem at all plug n play........you've got a bad cluster is my thought

 

mine is a denso cluster.
For some reason i bought 3 diffrent si cluster and none of them worked properly. No luck
