Review on 🔌 OLLGEN 3M/9.8ft Ultra Flat Low Profile 16 Pin Male to Female OBDII OBD2 Extension Cable for Car Diagnostics - Long Diagnostic Extender Cord Adapter by David Stewart

If you need to check the pins on the OBD 2 Data Link (DLC) connector, this is an absolute must. You don't want to be on your knees with a flashlight trying to figure out which pin is which. No, it's bad for the knees and bad for the soul! Its great length allows it to be in the engine compartment if necessary. To use a digital multimeter or similar you need very thin test leads as the holes are tiny. I went for the top drawer and bought the Pomona here at Revain (Pomona 6262-02 Extended Fine Pt Tip Adap Set (Set Red/Black), but there are cheaper alternatives.
