Wiring diagram

Need a 99 Civic cluster wiring diagram. I'm installing a tach on a friends DX. Anyone have any experience with Omori tachs??? Friend picked it up in Japan.

When you install it, for the tach RMP send line, either tap into the BLUE wire that's not connected to anything which is located ontop of the driver's side shock tower... OR you can locate a similar looking BLUE wire on the LEFT SIDE large wire harness that connects to the back of the cluster which is next to a small yellow harness.. LEFT SIDE meaning when the gauges are facing you when the cluster is bolted in. Hope that hepls you out.

what other wires do I need to tap into and what color are they?

why not just swap the whole cluster for an ex one? even an auto one with a tach, get some aftermarket gauges and bam your set dont see the auto shyt, it takes like 2 min and it just plugs in
