Fuel Pacer on 1977 Chrysler

Does anyone have a picture of where their Fuel Pacer vacuum switch on their 1977 (or there about) C-body formal? I believe mine was cut out of the harness at some point. I have a blue wire that registers 12 Volts when the ignition is on coming off the driver's inter-fender harness closer to the firewall. The car never had cruise so thinking this lead might be part of the fuel pacer. I'd like to figure it out. Any help would be appreciated.
