jerseybud, you may be correct in thinking wires might need to be longer but think about this. i think the van pcm sits right under hood and the motor sits farther back. might not be too many wires that need attention. i would be doing that swap and moving the van pcm to the blower motor area like 94 up. heck with putting pcm under drivers fender by battery. wires may have to be shortened then but could tie them up out of way. i wouldn't let that stop me from doing the swap.
