12 Pin Relay Wiring Diagram. 4 Pin Relay 4 pin relays use 2 pins 85 86 to control the coil and 2 pins 30 87 which switch power on a single circuit. 12V Relay Wiring Diagram 5 Pin Fitfathers 12 V Trucks 12 Volt Relay Wiring Diagram Wiring Diagram includes numerous comprehensive illustrations that display the link of assorted items.
It shows the components of the circuit as simplified shapes and the capacity and signal associates together with the devices. This video covers both 4 and 5 pin 12VDC relaysBest Connections - 12voltwireco. So based on our schematic and what Jayco wires as standard the pins we will be using on the 12 PIN plug are as follows - Hotwires x 2 - a 12 PIN Plug PIN 9 Hotwire for the fridge c 12 PIN Plug PIN 2 Hotwire for your electrics battery charger Earth x 2 - b 12 PIN Plug PIN 10 Fridge earth b 12 PIN Plug PIN 3 Normal trailer pin earth.
It shows the components of the circuit as simplified shapes and the capacity and signal associates together with the devices.
The Type B layout is arguably easier to work with as the connected terminals are in-line making the wiring easier to visualise. Note that each pin is numbered. This is a portion of my larger Relays Explained video. Looking at the diagram we see the pinout of a typical 12V relay.
