Help identifying harness/sensors

What harness is this and sensors? Comes out underneath steering shaft, tightly wrapped, extending to front. Also has relay on end. Other sensor is a two prong female type that may plug into something on my c100. Looks like that's the VSS.

The wide gray plug went to the cruise control servo. The relay is for the fog lights. The small two prong ties into the headlight harness. Unless it was a 6cyl originally, in which case there's a two wire plug to the pressure sensor in the power steering pressure hose.

Thanks!!! No 6cyl. Yeah I though it plugged into something on the headlight harness but wasn't for sure. Looks like it's tied into my green wires on headlights. Light green is high beams and brake lights., so guess it's brake lights??

The green and brown wires are the power/ground wires to the coil in the fog light relay. The matching plug should be in the headlight harness coming off C100. Normally they splice in to the marker lights and the high beams so the fogs cooperate with the parking, head, and high beam lights.
