The connector is similar to the pic.

The 1997's ( and 1996's I read) have one 10 pin connector like pictured AND a 16 pin connector to be used for diagnostics, not the 10 pin.

The 2nd pin on the 16 connector is blank.

I also tried the 2nd pin on the 10 connector, but it did not do anything. The check engine light remained on constant, and did not flash at all..

Hmmmmmmmmmm..... perhaps they have made some changes over the years!!!!

Thanks for your input!
