ok im getting a set of interceptors, and i also want to run my dash daq, i got a splitter cable, i havent got the gauges yet, but i tried with my dashdaq and laptop and wireless obd2 device for my ipod, well problem is only one thing will work at a time, either the dashdaq and the other stops working or the other device and the dashdaq stops working. so whats the point of a splitter cable if only one thing at a time works? and how do u get it working? it powers on all devices, just doesnt give me the info from the sensors
