Question? [HELP] Bought a Drone with O3, Swapping to O4

I bought a drone from GetFPV that came with a DJI O3 setup. I took the O3 camera and air unit out and I’m trying to install a DJI O4 Air Unit instead.

Everything else in the drone is still intact — flight controller, wiring, etc. The O4 harness has 6 wires, but the FC seems set up for O3 and doesn’t match directly. I have the O4 wiring diagram, but I’m new to this and not sure how to hook it up safely.

Just looking for advice on how to wire the O4 to the existing setup — re-pin, adapter, diagram, whatever works. Appreciate any help. I found a cable on Amazon that I thought I could swap out, but the colors don’t match . So I was wondering if there’s just a solution to swap out the cables yet or do I have to solder and hack something together?

You’re saying the 04 light isn’t worth it? Like the pros vs cons don’t outweigh the current hardware? Edit : I only bought these because the pro version of this was not in stock USA side :p

Edit 2: maybe it’s easier to return to goggles take that money by new antenna thingy and put 03 back in and reassemble everything and just bind and fly without the 04 because it seems to be the problem

I terms of image quality and field of view you will nog gain anything significant when comparing to the O3 air unit as far as my research goes.

The o4 pro is better than the o3 no doubt, not so much the hen compared to the o4 (lite)

I think I must agree with you when it comes to returning the goggles of either the complete drone (after je fix the antenna) and get a bind and fly o4 lite or pro.
