    Hello,
    I need to measure the power consumption of a device which is powered though am OBD port. I cannot dismantle the device so I need to monitor it's power consumption through outside means. Ideally, I could monitor the power usages at all time and record the measurements but the main objective is to be able to monitor the power usage in real time.
    Anyway, I was thinking that the best way to do so is to buy an OBD extension cable, cut it and plug the correct cables into a multimeter. Would this work or is there an easier and better way of doing so.

    Thank you for your time.

    Splicing into an extension seems like the simplest solution IMO..
    It would certainly work..
