Ok thanks I’m glad you explained it I can definitely change it over to a 4 pin already ordered the parts 

   So on the new 4 pin harness will I only be using the L wire on the harness?

Yes, only the L (lamp wire) is needed to turn it on and charge, you will want to connect the L wire to a 12volt ignition switched power source, or use a toggle switch to manually turn it on/off when needed (but you need to remember to turn it off when you shut the vehicle off because you dont want it on when the vehicle is off if you go the toggle switch route).

 

Also you need to run that size resistor in line with it because it will reduce the voltage and prevent the voltage regulator from burning up (this is something already done when its controlled by a vehicles computer, but when you are bypassing that and running your own power source you need to do it), this is a must or that new regulator will only last a few days at best).
