Having problems with your Cars & Trucks ?
2004 f350 fasher diogram - Cars & Trucks
Can't supply a diagram but I can tell you that 15A fuse 27 in the central junction box (CJB) applies power via a LT BLU/PNK wire to terminal 2 (the coil) of the indicator flasher relay in auxiliary relay box 1. 20A fuse 18 in the CJB applies power via a LTGRN/RED wire to the brake pedal position switch and terminal 3 (the relay arm). Terminal 5 of the relay connects the relay coil to ground (BLK wire). Terminal 1 of the relay supplies power via the LT BLU wire to the turn signals when the relay is closed. Terminal 4 supplies power via the WHT/RED wire to the hazard light circuit when the relay is open.
