I had to buy two breakout boxes to get mine and I don't need the second. Asking $75 +shipping. This will allow you to do a little more diagnostic work and gives you the ability to test things live since it plugs in inline with the ECM.

Good evening,
I realize this post is really old, but do you still have the breakout box that you'd like to sell? I'm looking for one for my 5.0 on my boat.
