i have a 2011 Ram. Putting the 6100Nex in it. I have the PAC as well and heard the speed input wire can connect to that. (?) maybe that makes sense because my cruise control is on my steering wheel. But not sure what to hook that pink wire to. The rest of the install is pretty much solved - well, a few question marks but none larger than the pink wire. Any suggestions? I looked at some of the other threads on it and no real findings on what and where exactly to tie the pink wire. Thanks!

Does the PAC adapter have a wire marked "VSS"?  If so, that's what you want.

It does. In the CAN interface group. Thanks!
