Rb25 s14 ecu not receiving speed signal

Postby JkRB25s14 » Mon Dec 04, 2017 7:13 am

Ok guys so i have a 1995 240sx with a series 1 rb25det. Wiring specialties oem harness. My issue is my speedo works correctly, besides having no illumination, but it reads spot on. Only issue is my z32 ecu that the car is tuned on is not receiving the signal. For some reason this issue didnt occur until i installed the wiring specialties harness. So since my speedo reads correctly i figured the circuit has to be good up till then, so i then check continuity from the connector that goes to the back of the cluster and then runs to the ecu. And that also has cont. Guys im lost please help
