Had the grill wrapped and when removing it and pulling the wiring harness thru the grill I pulled loose the passenger side wires from the plug to the headlight ... there are 5 wires ... driver side has three . Can someone point me to where all five wires go.. 2 are still connected but 3 are not on the top or middle of the three do all 3 go together on the middle / top of the plug

Looking at the above schematic each lamp requires a ground (pin 3) and low beam power and high beam power (pins 1 & 2) from the light switch. What Jeep did instead of running two separate sets of wires from the switch they use two wires from one lamp to provide the low beam and high beam power to the other lamp and this can be seen with the jumper wires running from pins 1 & 2 of one lamp to pins 1 & 2 of the other.

Where did you find the 3 pin and 5 pin connectors? Need to replace mine as no low beam lights.
