I need your guys help! im having some problems with my rpm to work correctly, so heres the thing, i have a 2000 gsr and was switching up the harness from OBD2b to OBD1 to work with my p28...everything starts up fine but the rpm gauge just goes dead...thinking that i could be a harness issue, i went and exchanged it but still the same problem. so if anyone can give me any suggestion or help i would really appreciate it thanks!
