Ford Truck Technical Drawings and Schematics - Section H - Wiring - Lights managed via forestall lamp transfer and flip signal indicator f100 via f350 trucks are ready with a mechanical plunger stop lamp switch that's set up at the brake pedal arm. This switch is designed for maximum loads usually much less than the fuses or circuit breaker inside the circuit, but ample for regular stop lamp hundreds. The most load is 12.5 amps and not at all are loads in excess of this value permissible.
The feed from introduced lighting to be managed by way of the headlamp switch should be terminated in a male bullet connector and be linked to the girl bullet take-out (brown twine -- 285 circuit) at the left-hand facet of the device panel harness (close to the emergency brake). If the car has roof marker lighting, this bullet might be occupied with the aid of the feed from the roof wires. In this case fabricate a "y" jumper to permit each connections to the single 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 happens, a portion of the brought lighting fixtures must be stressed out through a relay, feeding the relay coil from the headlamp transfer.
Please read: maximum of the wiring diagrams published on this page are scans of authentic ford diagrams, no longer aftermarket reproductions. Those had been scanned and published as very large documents, to keep their readability. The 1969 diagrams and all others marked with a purple asterisk (*) were sent to thru 1ec5f5ec77c51a968271b2ca9862907d from numerous resources, so their fine and/or size won't be as right or as special, however i still gratefully well known individuals who took the time to forward them for posting. Ultimately all diagrams posted right here can be hi-decision for less complicated analyzing.
1) the headlamp switches on all 1970 ford vehicles (besides "w" models) rent essential circuit breakers, one 12-amp for the headlight circuit and one 15-amp for auxiliary circuits. Connections to any factor inside the circuits managed with the aid of the headlamp transfer might be on the auxiliary circuit breaker, except connections to the #12 circuit (headlamp hi-beam, green twine/black stripe), the #13 circuit (headlamp low-beam, crimson wire/black stripe) and the #15 circuit (feed twine to the the dimmer transfer, red twine/yellow stripe. Connections to the 12-thirteen or 15 circuits (headlamp bulb circuits) must be avoided.
