Data link port
 

Hi all
1995 Burb 6.5L TD.

I'm replacing the key fob for my vehicle.
It only opens the door locks.

The "data link port" is different than the one's I see when looking for re-setting directions.

The ones I find are 16 hole and mine is a 12 hole.

The directions on the 16 are insert a wire in #4 and #8

But before I cross wires and start blowing fuses?? I want to make sure I cross the right holes.

Thanks, Jerry
