so i have a 1996 chevy s10 with a 4.3 and a 4l60e auto tranny.. i was wondering if anyone knew of any websites/ companies that offer wiring harnesses/ instruction/ direction for the swap.. im planning on a 5.3 with a nv3500 5 speed.. i have the 5.3 and computer hooked up to an auto tranny.. so i guess i was wondering how hard it woud be to swap the 5 speed onto the 5.3... i've done swaps on cars before, but never on a computer controlled/ smog regulated motor.... so some direction wold help out, and i know that a 5.7 vortec swap is easier.. its just not what i want
