Nismo Lcd Cluster And Ej1 Module

[arch nme]

hey guys i am hailing from the united states and need some help. i did a custom install with a gtir pulsar motor in a primera shell with autronic stand alone ecu.

I toped off the install with the nismo cluster and epson ej1 module and here is where i start having problems. As i searched the forums for wiring diagrams for the epson module i found that ALL diagrams had 5 wires.(red, black, orange, blue, green, white) HOWEVER my wiring harness on the ej1 has 7 wires it have an extra black wire (or what appears to be black in color)...

consequently i am only getting display readings for power, torque and rpm, i am not getting any speed display on the lcd screen but i have speed readings ont the speedometer....this is quiet puzzling as i connected direct wires to the speed sensor and connected them directed to the green wire and a black ground...and still got no speed readings...

can someone help

pleaseeeee!!!!!!!!!!!!
