SimpleThe 07 + 08 has one as well. Don't have a clue what it does.
On the old EGOs you had a barb to take the LPR hose from the front reg mount to the solanoid. With the FRM detatchable from the body you could get access to the barb. With the 07 and 08 having a FRM being at one with the body there is no way to get to this barb unless it is added in the way of a torpedo. You can take the hosing off and then remove the barb as it has an allen key slot in the front.
Might be a confusing way to describe it but I know what I mean
Hope that helps you guys
