The pinout is as follows, looking at the wiring from above:
- Green: Power from a fused 12v source.
- Red 1: Connect to a relayed circuit for the power line going to the locking differential
- Red 2: Connect to the dash light circuit, which allows the light in the switch to turn on when the dash lights are active.
- Black: Ground
Please Note: A relay must be used to provide power for the locking differential. Failure to do so can melt the switch or cause electrical damage to your vehicle.
Please see the product image for a visual guide to the pin-out connections.
