Wiring diagrams ford trucks - 1) the headlamp switches on all 1970 ford vehicles (except "w" models) hire vital circuit breakers, one 12-amp for the headlight circuit and one 15-amp for auxiliary circuits. Connections to any factor inside the circuits managed via the headlamp switch will be at the auxiliary circuit breaker, besides connections to the #12 circuit (headlamp hi-beam, green wire/black stripe), the #thirteen circuit (headlamp low-beam, pink cord/black stripe) and the #15 circuit (feed cord to the the dimmer switch, pink wire/yellow stripe. Connections to the 12-13 or 15 circuits (headlamp bulb circuits) should be prevented.
Please study: most of the wiring diagrams published in this web page are scans of authentic ford diagrams, now not aftermarket reproductions. These have been scanned and posted as very large documents, to keep their clarity. The 1969 diagrams and all others marked with a red asterisk (*) were despatched to through 1ec5f5ec77c51a968271b2ca9862907d from diverse assets, so their excellent and/or length may not be as exact or as specified, however i nevertheless gratefully acknowledge folks that took the time to ahead them for posting. Eventually all diagrams posted right here may be hi-decision for simpler studying.
The feed from brought lights to be managed by the headlamp switch should be terminated in a male bullet connector and be linked to the female bullet take-out (brown cord -- 285 circuit) at the left-hand aspect of the tool panel harness (close to the emergency brake). If the vehicle has roof marker lights, this bullet may be occupied by means of the feed from the roof wires. In this example fabricate a "y" jumper to permit both connections to the unmarried connector.
If the overall load on both headlamp circuit breaker exceeds the breaker rating, the headlamps or taillamps will cycle on and rancid indicating the overload. If this occurs, a part of the delivered lighting fixtures must be stressed out through a relay, feeding the relay coil from the headlamp switch.
Lighting controlled by means of forestall lamp transfer and flip signal indicator f100 via f350 vehicles are geared up with a mechanical plunger prevent lamp transfer that is mounted at the brake pedal arm. This switch is designed for max hundreds commonly less than the fuses or circuit breaker in the circuit, but ample for everyday forestall lamp masses. The maximum load is 12.5 amps and on no account are hundreds in excess of this fee permissible.
