I need a wiring diagram for the 88, 89, or 91 crx gauge cluster with a tach. One of the clusters is from a 89 DX and the other is from a 91 SI. I have a 88 crx and the cluster ground was burnt so I got a 91 si and a 89 dx but niether are working. I attempted to repin the clips but the conversion diagram I have is for the non-tach 90 dx so it was wrong. Then when I re-pined it back nothing but the speedo, turn signal, and bright lights indicator work. So I need a helms manual or the schematics for the clusters and wiring. Or someone who has done this before.

Thanks in advance....
