Headlight low beam out on driver side, broken wire (Violet/Purple with White Stripe) behind passenger headlight. Recommended fix?

My driver side headlight will not work on low beam, but works on high beam. After many hours of troubleshooting, I found that the power wire (violet/purple with white stripe), is broken behind the passenger side head light on the connector. I was curious what people have done to fix this? Is there any good You Tube videos, or how to guides to repair the wire that goes over to the driver side headlight? Below I are some things I did to find the problem. I appreciate any help or direction with this!




I. Things I tried during troubleshooting.

1. Replaced drivers side head light. No change, low beam still did not work.
2. Tested old and new head light on passenger side. Both work on high and low beam. Both head lights are good!
3. Replaced Multi-Function switch. Fixed Fog Lights, but low beam was still broken on driver side head light.
4. Replaced Multi-Function wire harness connector due to it crumbling in my hand. Low beam was still broken on driver’s side head light.
5. Checked voltage on drivers head light connector with a digital multi meter. ~12 DC volts on high and no voltage on low.
6. Cleaned connector on driver's side headlight with QD Electronics Cleaner spray. Still no 12 DC Volts on low beam connector. High beam(Red with Orange strip Wire) still works.
7. Tone generated wires. Found wires good from multi-function switch, to driver’s side connector, on fender wall, under brake fluid reservoir. Tone generated wires to passenger side connector. Passenger side passed both (Low and High beam) test. Noticed broken wire (violet/purple with white strip) on passenger side head light. Tone generated Passenger side to driver side. Ground and High beam electrical was good. Low beam wire had no tone. Went back to broken wire on passenger side, and tested to drivers side low beam. Got Tone! Bad and broken wire behind passenger headlight that supplies power to low beam on driver’s side!

No trick question, I just wasn’t sure if someone had a cool way to do it without doing the new pigtail. I apologize, I should have explained better. Like for example pull out the terminal and re crimp.

My wire broke off right on the H4 connector/terminal so I can't splice it back on. No wire left. Maybe too much shaking while off-roading ;-)! I'll try to up load a pic. I think your right, my option might be a new H4 pigtail, unless someone has a better way to recover my existing H4 Connector.

Looking up your Toyota headlight conversion recommendation also.

Any manufacturer recommendations on H4 Pigtail?

Thank you for the feedback!
