97 Blazer No Power to AC High Pressure Switch
 

Ive just recently replaced my entire Ac system. Compressor , condensor , high and low pressure switches , orifice tube etc, AC compressor would only kick on if i shorted out the low pressure switch. Ive recently found out that my high pressure switch connector is not recieving any current. I replaced all three relays on the back firewall passenger side and still no luck. Does anyone know where the wiring for the high pressure switch leads to? The closest answer I could find was one of the pins in the 32 pin connector that hooks to the computer on passenger side firewall. Any ideas on what I should do?
