Relay Operation
Located in the fuse box under the dash, the relays assist with
component operation like the cooling fan, fuel pump and EFI
system.
NOTE: The Rear Diff Solenoid Relay is mounted
separately, attached to the rear plastic LH panel
divider behind the driver’s seat.
NOTE: The Blackout Relay is secured to the wire
harness near the fuse box.
