MotorcraftNUMBER 87- 52SERVICE NEWS BULLETINSEPTEMBER , 1 9 87STANDARD WIRE AND COLOR CODE CHARTSFORD PASSENGER CARS AND LIGHT TRUCKSThis bulletin contains the standard circuit number charts for Ford Built Cars and Light Trucks. It is intended foruse only by technicians who are trained and skilled in servicing automotive electrical systems. The electricalcircuits are listed by circuit code number with a description or name of the circuit and color of the wire. Use thecharts for tracing and/or identifying individual circuits with the appropriate Ford shop manual, EVTM (Electricaland Vacuum Trouble Shooting Manual), or The Vacuum and Wiring Manual. All three manuals may bepurchased from Helm Inc., P.O. Box 07150, Detroit, Michigan 48207. Order forms for 1986 and 1987 modelyears are included at the back of this bulletin.VEHICLE APPLICATIONSFor example:BR/O is a brown wire with an orange stripe.R /Y D is a red wire with yellow dots.BK /W H is a black wire with white hash marks.PASSENGER CARSFORD & LINCOLN MERCURY1980-88 ALL CAR LINESMERKUR 1985-88 XR 4TiSCORPIO1988Color AbbreviationsBL BlueN NaturalBK BlackO OrangeBR BrownPK PinkDB Dark BlueP PurpleDG Dark GreenRRedTTanGR GreenW WhiteGY GrayYellowLB Light BlueYLG Light GreenIf a vehicle specific wire color in a connector doesnot match the diagram shown, it can usually beidentified by comparing the other colors shown atthe wire connectors.

The second color is thedot, hash, or stripe marking. If D or H is given, thesecond color is dots or hash marks. If there is noletter after the second color, the wire has a strioe.010284 Circuit wire Resistance wire Wire for optional conditions A group of wiresschematic clarity—used forThe information contained in this bulletin was in effect at the time the bulletin was approved for printing.
