Code reader build for W124
I saw the list of codes all around, but no one has specified HOW to build the actual code reader. I understand you tap off pin 8 or 14 from the ECU, but what is required to make the tool? I am really good with wiring and etc so I know I can build it myself. But can someone tell me how to do it?

Hi guys - the best reader we have found and use (and have used without issue for 10 years+) is offered the cheapest here: http://www.ebay.com/itm/321431790694...84.m1555.l2649

Great tool, lowest price and free shipping. Gotta love it.
