    OBD2 Extension cord works great but needs some kind of attachment so it doesn’t just dangle.

    I needed to hardwire my dash cam and car insurance monitor in the same spot. To me, my dash cam is more important as it has motion detection and runs 24/7 giving me peace of mind but on the other hand I get $10 off plus up to 25% off upon completion from my insurance company if I plug in their device to monitor my driving. Now I don’t need to choose. I have both. Easy installation, no issues.

    Worked out better than I thought it would. Plugged it in and tied the wiring neatly. hooked up my programmer, and still have an open port to plug into without unplugging the programmer. The state I live in wants to plug a device into everyone's vehicle so they can keep track of your mileage for a road tax. So with this cable I won't have cut back to the stock settings on my Duramax.

    Purchased a stage 1 chip for my '15 Lancer and also have a heads up display run off the obd as well. Saw this on the site and my prayers were answered. I got my tuner without sacrificing my awesome hud. Everything runs perfect too
