Yes it is part of the programmer cable on the OB2 end about 2" from the end the cable splits into a Y with a 4 prong connector/port. I was wondering what that was used for since it is now tucked under the console!
Ps. the OB2 cover that I came with the tuner when would I use it? Or is it only for when the tuner is not in the OB2 slot?
