Soooo... I am in the middle of swaping out my carb for a TBI setup from a 89 burb into my 73 k5. I got all the parts on but know I am realizing that it is a pain in the ass to wire. Soooo I got some questions. How does the in tank fuel pump hook up to the fuel pump relay? I have a sm465 and the burb that I pulled the ecm out of had a automatic. do I need a diffeerent chip? What wires from the fuel injection harnes to I have to hook up to my k5? Please help I want to go wheeling!!!
