I will be using my OBDII port for the power supply and speed data to my Valentine I radar detector. i would like to add the P3 vent integrated digital interface as well. It also plugs into the OBDII port. Does anyone have any experience using an OBDII splitter?

No knowledge eh?

Hi,

I use an ODB2 splitter all time the time. Mainly for reverse engineering.

Really all you need is CAN Hi/Lo and V+/V-.

Forgive my ignorance but are those specific pins within the OBDII?

Yes, those are pins within the connector. Modern BMW's only use the CAN pins and power.

I use one of these:

If I were to do something a little more permanent something smaller/more elegant is a better idea.

Thanks. After reading a few other threads about splitters, it sounds like both devices can't communicate simultaneously. Guess I'll just use a mirror tap for the V1.
