Need help finding a Crank/Run Wire for 5.3 swap - 87 Silverado - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm working on the wiring for my LS swap -wiring is not my strong suit. I have a premade harness which really helps, but I need to find a wire to connect the harness to that works in Run/Start. I tried reading a wiring diagram, but I'm lost.

I'm sure this is pretty straightforward for most - this is a 87 TBI Truck. I still have the original wire harness in place, its just all disconnected on the engine side (since the engine is gone). Is there a wire i can cut and splice into for Run/Start?
