Last question is, can I remove the Module without affecting the lighting?

Solved! It is a diode module for 4x4 lights and DRL.

Thank you for helping me solve the case.

All we did was ask questions and make you think

Last question is, can I remove the Module without affecting the lighting?

I assume so, but what about the 4x4 lights you mentioned, are those a "don't care"? Is yours a 2x4?

Regardless, study the schematic and figure it out! If you need some help, simply post the schematics (if you haven't already) and ask.
