A/C switches in Vortec Swap Questions

Hey Everyone,

I am currently finishing up a project and wanted to get some insight on some A/C questions I had. I have a 1990 c1500 which I have swapped in vortec 5.7 but have kept the 98 accessory drives, and retained the tbi setup. I have my condensor, 1998 compressor, accumlator, and lines. I noticed the vortec runs 3 pressure switches. One of the accumulator, one on the back of the compressor and another (no sure where it is located). I am not sure if the 1990 wiring harness supplied 3 pressure switches. I could only find the switch on the accumulator. How can I plump this system correctly to install all of the correct HP, LP, Switches?

Thanks -
