Need Help: OBDII Scanner does not plug in!!!
I drive a 98 Z28
Mods: (all work done by previous owner)
SLP Lid
Hand Ported Throttle body
MSD Ignition Coil Wires
Unknown Cat-Back
MAF Screen Popped off
Throttle body coolant by pass.
(pretty much every imaginable free-mod)
And what I expect to be some gear work...
Can anyone help me please?
Pics of the Pin pluggin.

This is the only diagram that I've managed to dig up from here.

By the looks of it, I have an extra pin on port 9, is that normal? Or do I have to check if the pins/wires are in the correct location?
