How do I get power to the obd connector

Most obd2 connectors are located right under drivers dashboard, or under fuse box cover,or another cover labeled obd2. Just Google your specific make and model. Good luck

FUSE check engine light

If you are trying to reset the light, use an obd code reader. Autozone can do this for free. If you are wanting to try resetting by powering it off, look for the ECM fuse in the fuse block. Or you can disconnect the battery for 5 minutes.

My obd2 isn't getting power what I do?

Check Pin #16 on the Data Link Connector (DLC) for battery voltage. (See Diagram)

If there is no battery voltage present check the fuse marked "OBD II" in the engine compartment fuse block. It is a 10 Amp fuse. If the fuse is good, repair the circuit between the fuse and pin #16 at the DLC.
If battery voltage is present at Pin 16 at the DLC, check for ground at pin 4 on the DLC. If ground is not present, repair the ground circuit between the DLC and Ground G202 located at the left side of the dash.
HINT: the easiest way to check BOTH of these at the same time is to use paper clips plugged into pin #16 and Pin #4 and connect a light bulb between the two. If the light illuminates brightly, power and ground are both OK.
If no problem with power or ground is detected at the DLC, check the Owner's Manual for your code reader.

My obd2 plug is not working i check the fuse and it's good what can it be

lots of times the connectors wear or bend, try pushing on the connector and holding it there while you scan it, you can also test to make sure its getting power at the correct terminal on the obd2 connector.

Autozone said the OBD2 connector.. or DLC.. whatever it's called, is not getting power to it when he tried plugging the tool in to see why my check engine light is on. He had asked if I hooked up a stereo...

Used a test light with key on, if no light at test light on both proms on fuse, remove and check blown fuse, also some may not have voltage, turn head light's on, could be head light fuse, should come on with light's on, but it's best to just pull fuse and check to make sure it's good or bad, lighter fuse does power your OBD2.
