I put a AW4 in my Javelin a few years ago. I will dig up my notes and wiring diagrams for you. The main thing I had to do is wire up the nutral saftey switch differently than how the stock Jeep system was. In the Jeep, they broke the ground wire and in the Javelin they broke the hot wire. We used a relay somhow to trick it.
Which enine are you using?
