I realized that there is two spout connectors on my 1987 f150 5.0 EFI, one at the driver side fender and the other next to the AC compressor, what do yall know of this?

 

I'm guessing one of them is for the option of a power steering pressure switch.

The power steering pressure switch wires will be black and white, and yellow and light green.
The SPOUT circuit wires will both be yellow and light green.
