Scanners and analyzers are modern wonders, but if you want to connect an auxiliary device like a scope or VOM you often have to find and backprobe the OBDII connections. These little breakout boxes are just the ticket for making connections to your OBDII interface datastream a breeze. They used to be expensive, but these days, they're fairly cheap on ebay -- about $20 shipped. Direct ship from China is about two/three weeks.
I'm in the process of upgrading some basic digital diagnostic equipment, and this is/was on top of the list.
