TBI Swap - Finding EST Wire - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just picked up an '83 with an '87 TBI engine swap. I would like to set the base timing and need to unplug the EST wire. I can't seem to find a tan/black wire anywhere. Where does the wire connect? I am thinking it might be easier to track it down if I know where it connects to. Does it go to the distributor? Is it normally a lone single wire or is it normally bundled with other wires.

Sorry about the basic question, but I am new to TBI engines

Thanks
Doug
