How to Make 4-Way to 12 Volt Power Outlet
Question:
Do you have a flat 4 plug to 12V plug cigarette lighter female? I want to have 15A 12V cooler in the bed of my truck. I do not have a 12V female plug in bed of truck so want to use trailer running lights lead for power and ground lead off flat 4 trailer plug mounted on bumper. I checked and it is 20 amp fuse for 2018 F150. Theory...The cooler will run off flat 4 power when I have the Truck running lights on. This is of course when I DONT have a trailer attached using the flat 4 plug... or can I still use flat 4 when the trailer attached is using the 7 plug connection?

Our best solution for that would be the part # 329-GC018 which is a cigarette lighter style of 12 volt connector that you could wire to the brown and white wires of a 4-way like # 002402. The brown would go to the red and the black to the white.
