Hello guys. I am new to this website today. I have searched everywhere on the internet. I am good with car wiring, and I have 1 last issue I need to resolve on my ECR33 1994. I have used NDS I and the cable to find and repair an issue successfully. Everything in the car works (except for HICAS; it is being deleted today using GKtech parts). I have noticed when I unplug the HICAS ECU that steering gets hard, so I left it plugged in. Anyway, that's not my issue. My speed reading in NDS I does NOT work (reads 0 kph) however it works on my cluster. I have read that there is a signal from the cluster to ECU. I want to short test this wire to make sure it is not broken but I don't have the means of identification (diagram). Can someone help me identifying the wire from cluster to ECU? Maybe previous owner cut this wire to remove speed cut or something. Thanks
