Ford Bronco Auxiliary Reverse Lamps Relay Wiring Diagram - Tap Methods A & B

Wiring diagram for reverse lamps showing 12V fused power, switched power, a relay, and lamp connections.

AI caption · Photo 13 of 50

This document is a simple hand-drawn wiring diagram, apparently for adding or wiring auxiliary reverse lamps, uploaded to the gallery of a 1987 Ford Bronco. The top portion shows a relay (drawn as a black square) with four labeled connections: '12V Fused' power input (red wire), 'Switched Power' output (red) feeding two lamp symbols that are each grounded, a 'Powered Switch' trigger input (blue), and a 'Reverse Lamps' connection (blue) shown going to ground. The middle of the page shows a blue wire labeled 'Reverse Lamps' with a small connector or splice symbol attached beneath it. The bottom portion shows two alternative wiring/splice arrangements labeled 'A' and 'B', each depicted as a horizontal blue wire with a black connector or tap attached — 'A' shows the tap on an unbroken wire, while 'B' shows the wire with a gap (cut) at the connector. The document contains no fuse amperage values, part numbers, wire gauge specifications, or vehicle year/model identification. A reader can learn the basic relay-triggered circuit concept: fused battery power switched by a relay that is triggered from the vehicle's existing reverse lamp circuit, powering additional lamps.

Frequently asked questions

How are the auxiliary reverse lamps powered in this diagram?
A relay receives a '12V Fused' input and outputs 'Switched Power' to two lamps, each of which is grounded. The relay is triggered via a 'Powered Switch' input connected to the 'Reverse Lamps' circuit.
What triggers the relay for the extra reverse lamps?
The diagram shows a 'Powered Switch' input on the relay wired (in blue) to the vehicle's 'Reverse Lamps' circuit, with the other relay coil side going to ground.
What are options A and B in the diagram?
They show two ways of attaching a connector/tap to the reverse lamp wire: option A shows the tap on an intact wire, while option B shows the wire cut at the connector.
Does the diagram specify fuse sizes or wire gauges?
No. It labels the power feed only as '12V Fused' and gives no amperage ratings, wire gauges, or part numbers.
