I agree, the motor is enough by itself. My starter truck was a mess, between lots of rust, cut up wiring, and crappy repairs. I have basically went down to a bare shell, did rockers, floorpans, half a trans tunnel and some bedside repairs before I even started anything new. Did frame reinforcments, links front and rear, 8.8 rear , relocated fuel tank and all new brakelines, and gutted the interior before starting the work on the motor swap.
After doing the motor placement and the 4l80 which is quite a bit larger than a aw4 lol, on to wiring. The eng harness was easy, used a lsx4u harness and worth the money, just hookup and go. Used a painless chassis harness for everything else and it took some time to make it work with all the Chrysler switches with the 98 xj interior. Done now, but several weekends of wiring all alone.
finishing up odds and ends now, hoses, translines and a punch list a mile long, but hope to finish upo the bodywork and paint over the winter and be able to play with it next year.
