Hello. I'm a first time poster, but have gleaned countless amounts of valuable info from this site. Thank you all. Now the Question. I'm adding edge juice w/ attitude as well as a pac brake to my truck. Both require to be plugged in to the obd2 port. (My truck is an auto trans) I have seen obd2 splitters on the web but don't know if the separate components will operate at the same time. Thanks for your input.

Yes. The ODBII port splitters work fine. The devices are prioritized by communications. So no need to worry typically all ODBII communication are dealt with by the first bit if its 1 or 0. http://articles.mopar1973man.com/general-cummins/34-engine-system/81-ccd-data-bus

Thanks Mike. I had referenced other forums which had tried to use the splitter. Some folks seemed to have problems with communications between tuners, ecm's, and radar detector jamming equip. through the splitter. It seems that dodge took care of that issue ahead of time with the ccd. I appreciate the article post, very helpful.
