This is a simple hand-drawn wiring diagram (drawn in a computer drawing program) uploaded to illustrate an ignition relay setup, filed under a 1985 Ford Bronco. The diagram shows four labeled elements: a battery (with + and - terminals marked), a small square labeled 'Relay' positioned near the battery's positive side, a circle labeled 'Ignition' (representing the ignition switch or key cylinder), and a thin pink/magenta wire labeled 'Ignition Hot'. A tall unlabeled rectangle in the center likely represents a firewall or dash panel that the wiring passes through/around. The routing shows a heavy red wire running from the battery positive terminal through the relay, across behind the panel, and up to the 'Ignition' circle. The thin pink 'Ignition Hot' wire runs from the relay area up and across the top of the diagram, presumably serving as the relay's trigger signal from the ignition circuit. The document contains no part numbers, wire gauge specifications, fuse ratings, terminal designations, year/model applicability statements, or amperage ratings. It is a conceptual illustration of how to wire a relay so the battery feeds the ignition through relay contacts, with the ignition-hot circuit energizing the relay.

Frequently asked questions

What components are shown in this ignition relay wiring diagram?
The diagram shows a battery (with + and - terminals labeled), a relay, an ignition (drawn as a circle), and a wire labeled 'Ignition Hot'.
How is the relay connected in this diagram?
The relay sits next to the battery's positive terminal. A red wire runs from the battery positive through the relay across to the ignition, while a thin pink 'Ignition Hot' wire runs from the relay area across the top of the diagram.
Where does the main power wire route in this diagram?
The red power wire runs from the battery positive terminal to the relay, then across (passing behind a central panel/rectangle) and up to the ignition.
Does this diagram specify wire gauges, fuse ratings, or part numbers?
No. The diagram only labels 'Ignition Hot', 'Ignition', 'Relay', and 'Battery' with + and - terminals; no gauges, fuses, or part numbers are shown.
