Yes I do need the 2. The 1 wont work. The problem is that I'm over the road right now and have no idea how to find one of these things for a decent price.

I have here a a good Nexiq USB link for sale .Asking price is $127.00 plus shipping to where ever it needs to go .This is spare unit that I no longer need to have hanging around .It does not come with any cables .
