Hi and
to the forum.
It looks like GM have revised the wiring harness for some reason, as they have changed from an eight pin connector to a ten pin connector, perhaps additional functions are going to be incorporated?
I'm sure it must be programmable, but it looks like it might need a new type of USB interface lead or perhaps an adapter cable to make it compatible with the earlier program lead?
I'll make some inquiries and see what I can find out.
