another wiring question

Ok I have almost all the wiring done on 1988 F150 5.0 but there is a female plug with a green/black tracer and black/yellow tracer on the back of the motor at the fuel rail and also a orange wire coming out of the same branch of the harness that I cant figure out any where they go. I have looked at the wiring diagram but cant figure where they plug into to any ideas?

I too have an 88 302. Off hand, my guess would be the Knock Sensor.

I think the plug you are looking at is the A/C Pressure switch plug C151 and the wires are black/yellow tracer and green/purple tracer.
The Orange wire is the ground for the O2 sensor.

Note that the wire colors for the knock sensor in 1988 are Light Green with a black tracer and Black with a white tracer.
