ok guys i have a 89 civic dx an i have the nd cluster but im trying to wire in the ns cluster and i can't seem to find the correct diagram to do so i found one an wired it the way i thought was correct an well everything work besides the speedo but when i turn on either side blinker both blinkers will flash an my temp gauge will rise instantly but when i turn off the blinker the temp gauge drops any help would be awesome thanks

 

What is an ns cluster?

 

an ns cluster is a different style cluster like nippon seiki rather than nippon denso

 

Never heard of the difference. I dont know what you are trying to dobut i am guessing its a jdm cluster. If this is the case just open the cluster up and switch the gauges inside.
