Re: '89 K1500 engine replacement help

Exactly what we were thinking of following the wire up. Unfortunately, it's buried inside the harness and it's going to be a pain getting inside of that mess of wires and then getting everything back together so it looks clean. I know worse case, we run a new wire from ignition.

Was just wondering about the old engine control module. In wiring diagrams the ignition switch has a wire going directly to it. Thinking since it's MIA, maybe it's preventing the starter circuit from being completed? I do not know much about the newer engines. I'm used to a engine only needing air, gas and spark...

As to using the TBI, that would be way to small for this engine. It's pretty built, should be pushing close to 400hp. We have a big Holley dbl pumper on it.
