Running into some shorts or something , went for a 4.3 tbi to a carberated 350 350 turbo, keeps draining battery checking fusable links, amd other wires was wondering if i still need the ecm i cut back the wires i didnt need anymore nothing is grounding out ? Anyone run into a problem like this , this isnt the first time ive swaped a engine like this never had problems like this before ? But this is the first tbi ive swaped out .
