Narrative:

Aircraft parked with many others on a 'closed' taxiway; i.e.; remote. Thunderstorm was in progress with moderate to heavy precipitation. Lighting was 'dim to nil'. As per SOP; [first officer (first officer)] first to arrive at aircraft to perform pre-flight inside and out. I arrived +45 later concurrent with the arrival of our 8 passengers. I performed normal outside check and boarded aircraft. We were given clearance to taxi from parked position to 'spot yellow' making normal turns for about 1 mile. Given taxi clearance to rw 17L and soon felt nose wheel shimmy. Requested and given clearance to stop and pulled aside (no other aircraft near us). I shut-down left engine and went outside while [first officer] remained at his station. I found the nose wheel steering pin not properly installed. I re-connected the assembly and considered the condition 'corrected' and with the concurrence of my flying partner decided the flight could continue as planned. Received ATC clearance to continue taxiing and completed the flight. Post flight inspection found the steering pin installed but the safety pin was not locked; i. East.; safety pin not perfectly functional. I completed a maintenance log book entry and notified maintenance as per SOP.[suggest] standardization of excel fleet to re-fit all nose wheel steering with 'permanent' steering pins.
