I used a test light to test each wire with lo beams on only 1 wire caused the test light to light up then when i turned on the hi beam the other wire lit up the yest light and the 3rd wire was just a common ground

Here is a little detective work for you!
First, identify the color of the ground wires, and that should be the same color for nearly all of the electrical things under the hood, but pay particular attention to things like lights.
There will be one wire of that color to every light.
Next you will likely have two wires, one for high beam, one for low beam, and those can be matched. Highs one color, lows another.
None of these wires should be hot with the headlights switched off, except that, during the 2001 automobile era, some cars and trucks had driving lights that were on whenever the car was moving!
God bless your efforts.
if you have H4 bulbs in the head lights ( 3 pins on the bulb then the centre pin is the earth wire and needs to be connected correctly. I am thinking that you have the lights connected incorrectly so that the lights are trying to earth out through each other and the earth pin is a power wire. remove the bulb and using a multimeter turn on the high beams and find which wire has the power. next turn on the low beams and find which wire has the power . the last wire should be a dead short to earth. Re-splice the wires accordingly.
You need a wiring chart to find the color code . however there are three wires , earth, low beam , high beam, to find same turn lights to high beam, with a vault meter neg. probe to earth probe each wire the live wire is high beam , dip lights and probe again live wire is low beam , other wire is earth wire.
Need your make and model. Usually low/high beam lights have 3 inputs. While high beam only lights have only two. Every make/model has different color schemes so that's why it's important to have full make/model. Someone with experience could easily do it with a multi-meter. It's all 12 volts. One ground, two hot wires one for low one for high.
should be three wires one ground one power for low beam one power for high beams
take a test light (if dont own one buy one there real cheap and useful) clamp test light to good ground turn on lights on low beam probe wires in connector until test light lights this will be low beam power
no switch to high beams should have power on other wire
Power for the headlights on the Left side (High and low beam.) comes from the same fuse... The ORANGE wire and the ORANGE/BLACK are the same, they connect in the harness. If you only lack the 12v to make the light work connect them at the headlight assembly.
If your low beam also lacks ground the Left low beam ground is shared with the right low beam ground... Run a wire from left low beam DARK BLUE to right low beam DARK BLUE/WHITE.
If its not working now then your cursed, seek a witch doctor.
with a test light ground connected to the positive battery terminal,,the one that will light up the light is the ground...the other 2 wires are the low and high beam. cut one of those,if the low beam is now on,you cut the high beam wire. if the high beam stays on,you cut the low beam wire.
