Ford Crown Victoria Electric Fan Relay Wiring Diagram - 2000 CV Relay Center

This is a hand-drawn (computer-drawn) wiring diagram showing how to wire an electric cooling fan using a 2000 Crown Victoria (CV) relay center, uploaded to a 1994 Ford Crown Victoria gallery. It depicts a 12V battery feeding a 12V+ constant circuit through a 10 Amp fuse and a 50 Amp Maxi-Fuse, an auxiliary relay (pins 30, 85, 86, 87, 87A), a high speed relay, a low speed relay, and a 30 amp circuit breaker, all feeding an electric fan. The auxiliary relay is triggered by the A/C high pressure switch (Grn/Orn wire): current flows from pin 30 to 87A until the A/C switch trips the coil, then current goes to 87. A legend lists the 2000 CV relay center wire colors: High Speed Relay: Pin 3/30-RD/BK, Pin 5/87-OG/LB, Pin 2/86-LG/VT, Pin 1/85-RD; Low Speed Relay: 30-YE, 87-YE/LB, 86-RD/LB, 85-BK. Notes state the low speed relay ground can go to a temp sensor, a switch, or both (recommending an ON/ON switch so low speed can be activated any time while still auto shutting down on high-side activation), and that pins 85 and 86 are reversed for the relay control center's existing wires.
