I heard the 3.4 down pipe would bolt into the j.. but it didnt on mine... for my cluster I just left the stock j computer alone and just wired up the sensors for my cluster.. I actaully have the v6 speed sensor hooked to both computers without any problems.. I heard you cant do that with the temp guage though.. something to do with ohms with be cut in half, most people run two temp sensors, one for the v6 pcm and one for the gauges.. good luck with the swap, mine was hard at all.. Hell i even wired it without a wiring diagram.. but then again i lost my torque converter lockup somewhere along the line..
