Hello everyone. I'm in the middle of a TBI conversion on a 59 chevy pu, and I hope this place can help. I've done a few 5.0 mustang converts that someone else modified the harness. I did a 2002 suburban 5.3 in a 52 GMC using painless. This is my first TBI that I'm modifying. It's half done, but there's a few wires I'm lost on and no one to set me straight. Onward and upward.
