CAS 1degree wire ? on E5 blacktop ecu

[USDRFTR]

I am installing BEE*R Rev limiter and I cannot find any diagrams for the E5 ecu. I need to hook up to the CAS 1 degree wire on ECU> All internet searches do not show my ECU> They all claim that wire is pin #31. I have an empty spot where # 31 goes. And the other CAS 1degree wire when hooked up to rev limiter, keeps the engine from starting.

My motor is a '98 180SX Kouki Blacktop with E5

Thanks
