Help identify this plug, please.

OBDII plug It's where you plug in to look at the various computer systems of the vehicle to help in troubleshooting

YEP....diagnostic port to hookup scanner/code reader.

OBD
On-Board Diagnostic LINK

As I thought. Many thanks for verifying.

Get a code reader plug it in and you can monitor all engine systems as you drive. I found the "sweet spot' for fuel mileage on my Cambria to be 62 to 65

MPH. Also IF you get a check engine light you can get the code and look it up online, this prevents being ripped off if you pay for repairs. I never leave

home without it. Also you can clear those pesky maintenance required lights built into the odometer.

Absolutely, it goes in my rig every trip.

If you've got a smartphone, you can get similar functionality for <$10 with a bluetooth reader + free OBD2 app. Cheap enough to keep one in every vehicle.

well I ordered an ELM 327 Interface that claims it "supports all OBDII protocols " and it doesn't work. I tried just about everything. THEY claim

you just plug it in, turn on your bluetooth and woola , well the woola was my hard earned dough flying out the window, hello.

Another vote for a Scangauge...it paid for itself the first season with it.
