I there any date (CSX number) related to this change? |
CSX2000 through CSX2200 had wiring design by AC Cars and made with British materials except early cars did change from Lucas voltage regulators to Ford ones at the same time early cars changed from Lucas generators to Ford ones. CSX2201 started the new specification and used Ford alternators. CSX2201 and later got main wiring harnesses (several different sections) designed by Ford and manufactured with American materials by one or more Ford suppliers. The American harnesses had to be shipped to AC Cars for installation. Most of the wiring in CSX2201 and up street cars was American but some ancillaries, specifically all the lights, had to have American made jumpers to connect American wiring to British looms that AC Cars used on the lamps. The German turn signal switch had to have its loom reterminated to plug into the Ford supplied main dash loom section.
Electrical ancillaries for CSX2201 and up street cars were all Ford or in some cases Cobra unique American made parts except the fore mentioned lamps, the fan motor in front of the radiator, wiper drive, tail lamp relay, turn signal “flasher”, heater/demister fan motor, turn signal indicator lamps, turn signal switch, horn switch, thermostatic fan switch, horns, and wiper switch if I counted them all up correctly just now. The charging system was all Ford, some of it very rare even in 1965. Some parts used in new car production were obsolete by the time the cars were completed and sold and not listed in the 1965 Shelby parts book.
British Wiring:
Long integral pigtails in plastic tube protective sheaths for each head lamp. (Cobra only)
Long integral pigtails in plastic tube protective sheaths for each front turn/park lamp. (Cobra only)
Cloth wrapped single wire (white w/blue dashed spiral trace) power source for turn signal switch. (Cobra only, I suspect that AC Cars provided this assembly.)
American Wiring:
The three largest Ford wire looms for a CSX2201 and later street cars have been commercially reproduced by more than one source. A few of the jumper looms were reproduced after I wanted some for CSX2551 and provided drawings. Ford supplied looms wise there were:
Under dash, with fuse block and instrument wiring. (XB-954435 Cobra only)
Engine bay, with connections for front light looms. (XB-954434 Cobra only)
Fire wall rearward, with connections for tag and tail lamp looms. (XB-954431 Cobra only)
Two each, one for each horn, horn power wires with male Lucas plug on one end and male Ford plug with same maker’s marks as other Cobra-Ford pieces on the other, connects Ford wiring to Lucas connections inside horn assemblies. (Cobra only)
Two each, one for each horn, horn ground wires with male Lucas plug on one end and female Ford ¼ inch ring terminal on the other, connects Lucas connections inside horn assemblies to the car chassis via one of the horn fixing bolts. (Cobra only)
One for the tag lamp, single Ford male plug for power and Ford ring terminal for grounding at the chassis end and two solder on male Lucas plugs inside the Lucas 467 tag lamp assembly. (Cobra only)
Two each to connect the Ford engine bay harness to the Lucas head lamp wiring. (Cobra only)
Two each short looms to connect the Ford chassis loom to the tail lamps. (modified Ford ACD-66603, Cobra only)
A left front marker/turn signal lamp jumper Ford to Lucas wiring. (Cobra only)
A right front marker/turn signal lamp jumper Ford to Lucas wiring. (Cobra only)
Bonding (ground wire) between tachometer and speedometer mounting clamps. (Cobra only)
Lucas windshield wiper switch to Ford harness #1, three wire gang. (Cobra only)
Lucas windshield wiper switch to Ford harness #2, three wire gang. (Cobra only)
Branched heater circuit, one path has minimal resistance and one path has about 2 ohm more resistance (on my old meter I get 2 ohm anyway). The fast motor speed power runs through the low resistance path and the slow motor speed power runs through the specific resistance wire path. The Delaney-Gallay made heater assembly blower motor has a power wire and a ground wire. These wires plug into the branched heater circuit loom assembly. The ground wire in the loom attaches to the same chassis point behind the dash fascia as the main instrument panel loom with a pan head chrome plated slotted sheet metal screw. (Cobra only)
Radiator cooling fan loom. (Cobra only)
Tachometer sender to tachometer loom. (Cobra only)
Positive battery cable. C4DF-14300-A FOMOCO (Ford production part.)
Negative battery cable. C2OF-14301-C SX FOMOCO (Ford production part.)
Starter cable. (looks like a Ford production part but so far I have not found one with the same dimensions)
Windshield washer pump extension wire assembly, custom made to suit with different cars using different wiring and crimp on terminals. (Cobra only)
Engine/transmission ground (at transmission mount bracket) wire. Modified FDD-14303-A SX FOMOCO (Ford production part made by Essex Wire®, modified for Cobra use – large ring terminal hole enlarged enough for one of the transmission mount bolts to pass through)
Major Parts:
Alternator assembly, 1963 model year design created for a specific 427 Ford charging system option package. (limited Ford production part)
Voltage regulator (early was a limited Ford production part and late a common Ford part)
Windshield washer pump (Ford production part)
Windshield washer push button switch (Ford production part)
Windshield wiper drive power feed circuit breaker (Ford production part)
Alternator warning lamp (based on a 1963 Ford truck part) (Cobra only)
High headlight beam indicator (collection of Ford production parts from different years and models) (Cobra only as an assembly)
Ignition switch assembly (Ford production parts)
Heater fan two speed switch (based on a Ford production part) (Cobra only)
Headlamp switch (Ford production part)
Tail lamp switch (Ford production part)
Oil and water temperature sender (made by Stewart Warner, might be Cobra only, I don’t remember anymore)
Thermal switch for radiator fan. Second of two revisions of Otter® M70 bi-metal switch. So far no application for this exact switch other than Cobras has been found.
Tachometer (made by SW under a Ford experimental engineering number)
(Cobra only)
Tachometer sender (made by SW under a Ford experimental engineering number)
(Cobra only)
Clock (based on a 1962 Galaxie design but with different steel and finish on front bezel) (Cobra only)
Starter solenoid (Ford production part – with production defect logo)
Horn relay (Ford production part)
Oil pressure sender (Stewart Warner)
Headlight dimmer switch (Ford production part)
Voltage regulators are something that very often gets changed on cars. Finding Cobras with the voltage regulator that it left the factory with or even just probably (doesn’t show any signs of ever being removed) isn’t frequent. I believe just two models were sent to AC Cars for installation on new cars being created. FoMoCo® C3XF-10316-C marked ones up into at least the high CSX23xx range and FoMoCo® C4TF-10316-D marked ones by at least the early CSX24xx range. There are not enough totally unrestored cars to review to get much finer timing than that.
