Adding a 4th light to your Raptor Grill kitUpdated 8 days ago
First, layout your main grill kit (3 lights & harness), your 4th light adapter harness, and the 4th light.
Now connect two of the Raptor lights to the two outside connectors from your harness.
Then connect the remaining 2 lights into the adapter as shown below.
After that you would connect the adapter into the 3rd connector on the harness so that all 4 lights are now connected to the harness.
At this point you have the 4 lights connected to the harness so you can proceed with the mounting of the lights and wiring of the harness to complete this install.
