I just pick up si gauges for my dx civic, now the problem is that the tack does not work. Am i misssing something here or do I need to do some rewiring? I need help! Thanxs

 

I Have a 91 dx and I swapped for a si cluster. I had no problems,tach works fine, only connecting the speedo cable was kinda tricky.Your dx should be prewired for the tach and should'nt require any mods.Just connect the 2 harness to the cluster and speedo cable and it should work.
