One of the most crucial components of an RV’s electrical system is the 7 spade wiring diagram. In this comprehensive guide, we’ll discuss everything you need to know about 7 spade wiring diagrams for your RV.
What is a 7 Spade Wiring Diagram?
A 7 spade wiring diagram is a wiring diagram that shows how to connect the 7-way trailer connector used on most RVs. The 7 spade wiring diagram is used to connect the RV’s electrical system to the towing vehicle’s electrical system. The 7 spade wiring diagram is also referred to as a 7-pin trailer plug wiring diagram or a 7-way RV trailer connector wiring diagram.
The 7 spade wiring diagram consists of seven pins, each of which has its function. The pins are labeled with numbers, which correspond to the functions they perform. The seven pins are:
| Pin | Function |
|---|---|
| 1 | Ground |
| 2 | Electric Brakes |
| 3 | Left Turn/Stop |
| 4 | Right Turn/Stop |
| 5 | Taillights |
| 6 | Reverse Lights |
| 7 | 12V Battery |
Pin 1: Ground
Pin 1 is the ground pin. It connects the trailer’s electrical system to the towing vehicle’s chassis ground. This pin is crucial for ensuring proper electrical grounding, which is important for safety and proper electrical functioning.
Pin 2: Electric Brakes
Pin 2 is used to connect the RV’s electric brakes to the towing vehicle’s brake controller. This pin sends electric signals to the trailer’s brakes, allowing the towing vehicle to control the RV’s braking system.
Pin 3: Left Turn/Stop
Pin 3 is used to connect the RV’s left turn and stop signal to the towing vehicle’s left stop and turn signal. This pin allows the RV to signal to other drivers when it is turning or coming to a stop.
Pin 4: Right Turn/Stop
Pin 4 is used to connect the RV’s right turn and stop signal to the towing vehicle’s right stop and turn signal. This pin allows the RV to signal to other drivers when it is turning or coming to a stop.
Pin 5: Taillights
Pin 5 is used to connect the RV’s taillights to the towing vehicle’s taillights. This pin allows the RV to be visible to other drivers on the road, especially at night or in low light conditions.
Pin 6: Reverse Lights
Pin 6 is used to connect the RV’s reverse lights to the towing vehicle’s reverse lights. This pin allows the RV to signal to other drivers when it is backing up or maneuvering in reverse.
Pin 7: 12V Battery
Pin 7 is used to connect the RV’s 12V battery to the towing vehicle’s charging system. This pin allows the RV’s battery to be charged while the RV is being towed, ensuring that the RV’s electrical system remains fully charged and functional.
