Excellent, Thank You for the confirmation! I needed to drive out to Washington State and picked up the part in Oklahoma and it has the fourth beige wire like the driver's side.
But haven't been able to get back to Florida to try it out. Cannot wait to get back and install the new LED headlamps!
Please let us know how you resolved this issue. I have a 2021 Gladiator Willys Diesel and my passenger side also only has three wires; driver side has a fourth beige wire in number 5 position. So I expect to see the same behavior as you.
