Great thread! I've finally read through it all. Lots of good info. Pretty much every question I had was already answered. I've messed with TBI engines a bit and I'm pretty familiar with the components and their functions. After much reading and research I've just started my own project and with the help of this thread I've got my donor harness rewired for my application. It's a 92 454 harness originally equipped with an auto trans. Here's my first hangup. There no wire in the B7 pin. The first page of this thread indicates that this is designated "ESC, Knock Sensor signal to ECM". This harness has no ESC or KS plug in the harness. The harness had not been tampered with. Is the ESC not necessary?
Great diagrams and schematics!!!
