    Hi I’ve converted my vx ss 5.7 from auto to manual and I’ve still got the auto loom in can anyone tell me how to get my speedo to work the plug wasn’t long enough to plug into the speedo sensor so I turned it up the other way and managed to plug it in but it only says 40 kmh when I’m doing 100 kmh is there some other way to get it working do I need to calibrate it some how or do I have to turn the sensor back to original position thanks

    I believe you need to change a setting in the PCM.

    Ok thanks I’m guessing with that plug on the gear box that I had plugged in where the sensor is that’s definitely the speed sensor so all I need now is to get someone to change something on the pcm
