Qamar bhai i installed different versions.
NDSI and nds111 pe it says setting protocol setting long and scanner light blinks bar 70% hojata hai then it says ini failed.
I've connected the scanner grip accordingly.
Have connected kline, 12v and ground.
Haven't connected rpm and chk wire yet. I don't know the error is because of that. I think i should first visit samandar khan and pay him for scanning and scan it on the proper scanner first.
