I am new to this "SVX Thing" but rapidly becoming a groupie!

I just bought a 97 LSI and want to check for codes.

I've read the posts about the blue wires, and 2nd pin on the black diagnostic connector.

Problem:

On my 1997, the second pin on the connector (yes on top from the left, notch up) has no wire going to it !!

Do I need to use the OBD II connector on the dash instead?

Guidance here is much appreciated!

I saw a previous post mentioning the same, but could not find the resolution.

Happy Holidays to all!!!
