In my car which looks untouched in that corner, one low pressure switch wire makes 3 loops around the aluminum AC line in your picture then is zip tied to the bundle from the glow relay (the big bundle in your picture). The big bundle is zip tied to the lonely bracket in your picture. The pressure switch wire is zip tied to the big bundle closer to the compressor. The other pressure switch wire goes into a sheath that tucks under the port headlight. I'd take a picture but everything within spitting distance of the belt is coated with leaky front crank seal effluent.
