Kent is right
The only change you need to make is put the high and low wires on the same line because you only have one lamp not two as in the original lights
If you want to set wires back in look at the other plug on the other side
or match the wires on the light to plug that you mixed up
The 4 wire plug is for the park /turn signal lights below
If you are not fimiliar with wiring get a frend to ring it out
you don't want to burn it up with a dead short to the system
