alright guys i got my self a full lt1swap from a 95 impala and i need to know who out there make harnesses for it. Street And Performance has one for 750, Speartech for 650, superior harness, and painless. right now im leaning for speartech or superior as the customer service seems good. it seems good quality and a fair price. What are your opinions on these and what other companies are out there? with these harnesses are they trully plug and play? i get a fealing ittle plug into the motor but im still gonna have to splice in the guages, and all the other accessories. Am i right on this one?
