OBD-II splitter cable

Need to plug multiple things into your OBD-II port? This makes that job easy. With a tidy 90 degree plug, so it doesn't stick down into the footwell, and two new ports that can be secured under the dash, it doesn't get much easier than this. 

Bear in mind that OBD-II / CAN protocols often have a priority to them, so just because you plug two things in doesn't mean they'll both work. Have an iDash gauge and a simple insurance monitor? They should both work great. Have an iDash and you want it plugged in while you're reflashing your ECU? That almost definitely won't work (and might damage your ECU). If you're not sure about your situation, ask us and we can offer an opinion (although we might not have experience with your specific combination of parts).
